The ADuM524x are dual-channel digital isolators with isoPower integrated, isolated power. Based on the Analog Devices, Inc. iCoupler® technology, a chip-scale DC/DC converter provides up to 50 mW of regulated, isolated power at 5 V, which eliminates the need for a separate isolated DC/DC converter in low power isolated designs. The Analog Devices chip-scale transformer iCoupler technology is used both for the isolation of the logic signals as well as for the DC/DC converter. The result is a small form factor, total isolation solution.The ADuM524x isolators provide two independent isolation channels in a variety of channel configurations, operating from a 5 V input supply. ADuM524x units may be used in combination with other iCoupler products to achieve greater channel counts.

The ADuM6132 is an isolated half-bridge gate driver that employs the Analog Devices, Inc., iCoupler® technology to provide an isolated high-side driver with an integrated 275 mW high-side supply. This supply, provided by an internal isolated dc-to-dc converter, powers not only the ADuM6132 high-side output but also any external buffer circuitry that is commonly used with the ADuM6132. This functionality eliminates the cost, space, and performance issues associated with external supply configurations such as a bootstrap circuit.The architecture of the ADuM6132 isolates the high-side channel and the high-side power from the control and low- side interface circuitry. Care has been taken to ensure close matching between the high-side and low-side driver timing characteristics to reduce the need for a dead time margin.In comparison to gate drivers that employ high voltage level translation methodologies, the ADuM6132 offers the benefit of true, galvanic isolation. The differential voltage between high-side and low-side channels can be as high as 800 V with good insulation lifetime (see Table 12).isoPower® uses high frequency switching elements to transfer power through its transformer.

The LT3080-1 is a 1.1A low dropout linear regulator that incorporates an internal ballast resistor to allow direct paralleling of devices without the need for PC board trace resistors. The internal ballast resistor allows multiple devices to be paralleled directly on a surface mount board for higher output current and power dissipation while keeping board layout simple and easy. The device brings out the collector of the pass transistor to allow low dropout operation—down to 350mV—when used with multiple input supplies. The LT3080-1 is capable of supplying a wide output voltage range. A reference current through a single resistor programs the output voltage to any level between zero and 36V. The LT3080-1 is stable with 2.2μF of ceramic capacitance on the output, not requiring additional ESR as is common with other regulators.Internal protection includes current limiting and thermal limiting. The LT3080-1 regulator is offered in the 8-lead MSOP (with an Exposed Pad for better thermal characteristics) and 3mm × 3mm DFN packages.

The LTC2452 is an ultra-tiny, fully differential, 16-bit, analog-to-digital converter. The LTC2452 uses a single 2.7V to 5.5V supply and communicates through an SPI interface. The ADC is available in an 8-pin, 3mm × 2mm DFN package or TSOT-23 package. It includes an integrated oscillator that does not require any external components. It uses a delta-sigma modulator as a converter core and has no latency for multiplexed applications. The LTC2452 includes a proprietary input sampling scheme that reduces the average input sampling current several orders of magnitude when compared to conventional delta-sigma converters. Additionally, due to its architecture, there is negligible current leakage between the input pins.The LTC2452 can sample at 60 conversions per second, and due to the very large oversampling ratio, has extremely relaxed anti-aliasing requirements. The LTC2452 includes continuous internal offset and full-scale calibration algorithms which are transparent to the user, ensuring accuracy over time and over the operating temperature range. The converter has an external REF pin and the differential input voltage range can extend up to ±VREF .Following a single conversion, the LTC2452 can automatically enter a sleep mode and reduce its supply current to less than 0.2μA. If the user reads the ADC once a second, the LTC2452 consumes an average of less than 50μW from a 2.7V supply.Applications System Monitoring Environmental Monitoring Direct Temperature Measurements Instrumentation Industrial Process Control Data Acquisition Embedded ADC Upgrades

The OP27 precision operational amplifier combines the low offset and drift of the OP07 with both high speed and low noise. Offsets down to 25µV and drift of 0.6µV/°C maximum make the OP27 ideal for precision instrumentation applications. Exceptionally low noise, a low 1/f noise corner frequency, and high gain (1.8 million), allow accurate high-gain amplification of low-level signals. A gain-bandwidth product of 8MHz and a 2.8V/µsec slew rate provides excellent dynamic accuracy in high-speed data-acquisition systems. A low input bias current of ±10nA typical is achieved by use of a bias-current-cancellation circuit. The output stage has good load driving capability. A guaranteed swing of ±10V into 600 Ohms and low output distortion make the OP27 an excellent choice for audio applications. PSRR and CMRR exceed 120dB. These characteristics, coupled with long-term drift of 0.2µV/month, allow the circuit designer to achieve performance levels previously attained only by discrete designs.

The AD4001/AD4005 are high accuracy, high speed, low power, 16-bit, Easy Drive, precision successive approximation register (SAR) analog-to-digital converters (ADCs) that operate from a single power supply, VDD. The reference voltage, VREF, is applied externally and can be set independent of the supply voltage. The AD4001/AD4005 power scales linearly with throughput. Easy Drive features reduce both signal chain complexity and power consumption while enabling higher channel density. The reduced input current, particularly in high-Z mode, coupled with a long signal acquisition phase, eliminates the need for a dedicated ADC driver. Easy Drive broadens the range of companion circuitry that is capable of driving these ADCs (see Figure 2 in the data sheet).Input span compression eliminates the need to provide a negative supply to the ADC driver amplifier while preserving access to the full ADC code range. The input overvoltage clamp protects the ADC inputs against overvoltage events, minimizing disturbances on the reference pin and eliminating the need for external protection diodes. Fast device throughput up to 2 MSPS allows users to accurately capture high frequency signals and to implement oversampling techniques to alleviate the challenges associated with antialias filter designs. Decreased serial peripheral interface (SPI) clock rate requirements reduce digital input and output power consumption, broadens digital host options, and simplifies the task of sending data across digital isolation.
