EVAL-AD5570SDZ
Analog Devices Inc.The AD5570 is a single 16-bit serial input, voltage output DAC that operates from supply voltages of ?11.4 V up to ?16.5 V. Integral linearity (INL) and differential nonlinearity (DNL) are accurate to 1 LSB. During power-up, when the supply voltages are changing, VOUT is clamped to 0 V via a low impedance path.The AD5570 DAC comes complete with a set of reference buffers. The reference buffers allow a single, positive reference to be used. The voltage on REFIN is gained up and inverted internally to give the positive and negative reference for the DAC core. Having the reference buffers on-chip eliminates the need for external components such as inverters, precision amplifiers, and resistors, thereby reducing the overall solution size and cost.The AD5570 uses a versatile 3-wire interface that is compatible with SPI?, QSPI?, MICROWIRE?, and DSP? interface standards. Data is presented to the part as a 16-bit serial word. Serial data is available on the SDO pin for daisy-chaining purposes. Data readback allows the user to read the contents of the DACregister via the SDO pin.Features on the AD5570 include LDAC which is used to update the output of the DAC. The device also has a power-down pin (PD), allowing the DAC to be put into a low power state, and a CLR pin that allows the output to be cleared to 0 V.The AD5570 is available in a 16-lead SSOP.PRODUCT HIGHLIGHTS 1 LSB maximum INL and DNL.

AD5600 Evaluation Board
Analog Devices Inc.This user guide details the operation of the EVAL-AD5600PMDZ for the AD5600 voltage output, digital-to-analog converter (DAC).
The EVAL-AD5600PMDZ is designed to help users quickly prototype AD5600 circuits and reduce design time. The AD5600 operates from a single 2.7 V to 5.5 V supply. The EVALAD5600PMDZ also incorporates high temperature ADR225 voltage reference and AD8634 buffer.
The EVAL-AD5600PMDZ interfaces to the USB port of a PC via a system demonstration platform (SDP) board and the SDP-PMDIB1Z board. The ACE software is available for download from the EVAL-AD5600PMDZ product page to use with the evaluation board to allow the user to program the AD5600. A peripheral module (PMOD) connection is also available to allow the connection of microcontrollers to the evaluation board without the SDP board. Note that when a microcontroller is used through the PMOD connection, the SDP board must be disconnected, and the user is unable to operate the ACE software.
The EVAL-AD5600PMDZ is compatible with any Analog Devices SDP board, which can be purchased separately. A typical connection between the EVAL-AD5600PMDZ, the EVAL-SDP-CB1Z board (SDP-B controller board), and the SDP-PMD-IB1Z is shown in Figure 1.

Analog Devices Inc.The AD7292 contains all the functionality required for general-purpose monitoring of analog signals and control of external devices, integrated into a single-chip solution. The AD7292 features an 8-channel, 10-bit SAR ADC, four 10-bit DACs, a ?1?C accurate internal temperature sensor, and 12 GPIOs to aid system monitoring and control.The 10-bit, high speed, low power successive approximation register (SAR) ADC is designed to monitor a variety of single-ended input signals. Differential operation is also available by configuring VIN0 and VIN1 to operate as a differential pair.The AD7292 offers a register programmable ADC sequencer, which enables the selection of a programmable sequence of channels for conversion.Four 10-bit digital-to-analog converters (DACs) provide outputs from 0 V to 5 V. An internal, high accuracy, 1.25 V reference provides a separately buffered reference source for both the ADC and the DACs.A high accuracy band gap temperature sensor is monitored and digitized by the 10-bit ADC to give a resolution of 0.03125?C. The AD7292 also features built-in limit and alarm functions.The AD7292 is a highly integrated solution offered in a 36-lead LFCSP package with an operating temperature range of ?40?C to +125?C.APPLICATIONS Base Station Power Amplifier (PA) Monitoring and Control RF Control Loops Optical Communication System Control General-Purpose System Monitoring and Control
