DC536A-B: Demo Board for the LTC4211 Hot Swap Controller with Multifunction Current Control.

Demonstration circuit 536B is a hot swap controller with multifunction current control featuring the LTC4211. The DC536B-A is configured to operate with up to 7A load and DC536B-B up to 20A load.

The DC539B demo board is used to evaluate the LTC5509, RF power detector with integrated output buffer and voltage reference. The LTC5509 converts an RF input signal at pin 6 (RF) to a DC voltage at pin 3 (VOUT). The RF input frequency range is 300 MHz to 3000 MHz. Maximum input power is 8 dBm. The output voltage at VOUT will start at an initial DC value of typically 250mV. When the RF signal is applied the output voltage will increase.

Demonstration circuit 542 is a dual output, dual phase synchronous step-down controller, featuring the LTC3728EG. Output #1 can be configured for either 5.0V or 3.3V and output #2 can be configured for either 3.3V or 2.5V. The maximum load for both rails is 12A. The input voltage range of the DC542 is 8V to 24V. The DC542 also contains a footprint for a 5.5V boost converter bias supply whose output is connected to EXTVCC. See the “Optional Bias Supply” section for more details.

The AD5332?/ AD5333?/ AD5342 / AD5343?are dual 8-,10-,and 12-bit DACs. They operate from a 2.5 V to 5.5 V supply consuming just 230 ?A at 3 V, and feature a power-down pin, PD that further reduces the current to 80 nA. These devices incorporate an on-chip output buffer that can drive the output to both supply rails, while the AD5333 and AD5342 allow a choice of buffered or unbuffered reference input.PRODUCT HIGHLIGHTS Available in a 28-lead TSSOP package Low power, single supply operation from 2.5 V to 5.5 V supply Consumes 0.69 mW at 3 V and 1.5 mW at 5 V On-chip output buffer can drive output to both supply rails Allows a choice of buffered/unbuffered reference input Programmable output range 0-VREF or 0-2VREF (via GAIN pin)

The AD5362 / AD5363 contains 8, 16/14-bit DACs in a single, 56-lead, LFCSP or 52-lead LQFP package. It provides buffered voltage outputs with a span 4 times the reference voltage. The gain and offset of each DAC can be independently trimmed to remove errors. For even greater flexibility, the device is divided into two groups of 4 DACs, and the output range of each group can be independently adjusted by an offset DAC.The AD5362 / AD5363 offers guaranteed operation over a wide supply range with VSS from -4.5 V to -16.5 V and VDD from +8 V to +16.5 V. The output amplifier headroom requirement is 1.4 V operating with a load current of 1 mA.The AD5362 / AD5363 has a high-speed serial interface, which is compatible with SPI?, QSPI?, MICROWIRE?, and DSP interface standards and can handle clock speeds of up to 50 MHz. All the outputs can be updated simultaneously by taking the LDAC input low. Each channel has a programmable gain and an offset adjust register.Each DAC output is amplified and buffered on-chip with respect to an external SIGGND input. The DAC outputs can also be switched to SIGGND via the CLR pin.APPLICATIONS Instrumentation Industrial Control System Level setting in automatic test equipment (ATE) Variable optical attenuators (VOA) Optical line cards

The AD5410/AD5420 are low cost, precision, fully integrated 12-/16-bit converters offering a programmable current source output designed to meet the requirements of industrial process control applications. The output current range is programmable at 4 mA to 20 mA, 0 mA to 20 mA, or an overrange function of 0 mA to 24 mA. The output is open-circuit protected. The device operates with a power supply (AVDD) range from 10.8 V to 60 V. Output loop compliance is 0 V to AVDD ? 2.5 V.The flexible serial interface is SPI, MICROWIRE?, QSPI?, and DSP compatible and can be operated in 3-wire mode to minimize the digital isolation required in isolated applications.The device also includes a power-on reset function, ensuring that the device powers up in a known state, and an asynchronous CLEAR pin that sets the output to the low end of the selected current range.The total unadjusted error is typically ?0.01% FSR.Applications Process control Actuator control PLC HART network connectivity

The AD5426 / AD5432 / AD5443 EVAL-AD5443SDZ / EVAL-AD5446SDZ / EVAL-AD5453SDZ are CMOS 8-, 10-, and 12-bit current output digital-to-analog converters (DACs), respectively. These devices operate from a 2.5 V to 5.5 V power supply, making them suitable for battery-powered applications and many other applications.These DACs use a double buffered, 3-wire serial interface that is compatible with SPI, QSPI?, MICROWIRE?, and most DSP interface standards. In addition, a serial data out pin (SDO) allows for daisy-chaining when multiple packages are used. Data readback allows the user to read the contents of the DAC register via the SDO pin. On power-up, the internal shift register and latches are filled with 0s and the DAC outputs are at zero scale.As a result of manufacturing on a CMOS submicron process, the parts offer excellent 4-quadrant multiplication characteristics with large signal multiplying bandwidths of 10 MHz. The applied external reference input voltage, VREF, determines the full-scale output current. An integrated feedback resistor, RFB, provides temperature tracking and full-scale voltage output when combined with an external current to voltage precision amplifier.The AD5426 / AD5432 / AD5443 EVAL-AD5443SDZ / EVAL-AD5446SDZ / EVAL-AD5453SDZ DACs are available in small, 10-lead MSOP packages.The EVAL-AD5443SDZ / EVAL-AD5446SDZ / EVAL-AD5453SDZ evaluation board is available for evaluating DAC performance.
