Demonstration circuit 1326A consists of three voltage regulators; a synchronous boost, a synchronous buck and a linear LDO. Jumpers are provided for selecting a total of nine output voltages (3 boost output voltages: 1.8V/3.3V/5V, 3 buck output voltages: 1.2V/1.5V/1.8V, and 3 LDO output voltages: 1.5V/2.85V/3V). The high efficiency DC/DC converters feature 700mA switches for the boost, 250mA for the buck and a 100mA rating for the LDO regulator. With a light load, the boost converter can startup with an input voltage as low as 700mV and once started, the input can go as low as 500mV while maintaining a regulated output. That maximum boost and buck input voltage is 5.5V. The buck converter requires 1.8V minimum input.

Selectable address and configurable functionality give the LTC2990 flexibility to be incorporated in various systems needing temperature, voltage or current data. The LTC2990 fits well in systems needing sub-millivolt voltage resolution, 1% current measurement and 1?C temperature accuracyor any combination of the three.Applications Temperature Measurement Supply Voltage Monitoring Current Measurement Remote Data Acquisition Environmental Monitoring

The AD4003/AD4007/AD4011 are high accuracy, high speed, low power, 18-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 AD4003/AD4007/AD4011 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. The SPI-compatible serial user interface is compatible with 1.8 V, 2.5 V, 3 V, and 5 V logic by using the separate VIO logic supply.APPLICATIONS Automated test equipment Machine automation Medical equipment Battery-powered equipment Precision data acquisition systems Instrumentation and control systems

The AD4030-24 is a 2 MSPS successive approximation register (SAR) analog-to-digital converter (ADC) with Easy Drive?. With a guaranteed maximum ?0.9 ppm integral nonlinearity (INL) and no missing codes at 24-bits, the AD4030-24 achieves unparalleled precision from ?40?C to +125?C. Figure 1 in the data sheet shows the functional architecture of the AD4030-24.A low-drift, internal precision reference buffer eases voltage reference sharing with other system circuitry. The AD4030-24 offers a typical dynamic range of 109 dB when using a 5 V reference. The low noise floor enables signal chains requiring less gain and lower power. A block averaging filter with programmable decimation ratio can increase dynamic range up to 155.5 dB. The wide differential input and common mode ranges allow inputs to use the full ?VREF range without saturating, simplifying signal conditioning requirements and system calibration. The improved settling of the Easy Drive analog inputs broadens the selection of analog front-end components compatible with the AD4030-24. Both single-ended and differential signals are supported.The versatile Flexi-SPI serial peripheral interface (SPI) eases host processor and ADC integration. A wide data clocking window, multiple SDO lanes, and optional DDR data clocking can reduce the serial clock to 10 MHz while operating at a sample rate of 2 MSPS. Echo clock mode and ADC host clock mode relax the timing requirements and simplify the use of digital isolators.The BGA package of the AD4030-24 integrates all critical power supply and reference bypass capacitors, reducing the footprint and system component count, and lessening sensitivity to board layout.APPLICATIONS Automatic test equipment Digital control loops Medical instrumentation Seismology Semiconductor manufacturing Scientific instrumentation
