The ADP5071 is a dual high performance dc-to-dc regulator that generates independently regulated positive and negative rails.
The input voltage range of 2.85 V to 15 V supports a wide variety of applications. The integrated main switch in both regulators enables generation of an adjustable positive output voltage up to +39 V and a negative output voltage down to −39 V below input voltage.
The ADP5071 operates at a pin selected 1.2 MHz/2.4 MHz switching frequency. The ADP5071 can synchronize with an external oscillator from 1.0 MHz to 2.6 MHz to ease noise filtering in sensitive applications. Both regulators implement programmable slew rate control circuitry for the MOSFET driver stage to reduce electromagnetic interference (EMI).
Flexible start-up sequencing is provided with the options of manual enable, simultaneous mode, positive supply first, and negative supply first.
The ADP5071 includes a fixed internal or resistor programmable soft start timer to prevent inrush current at power-up. During shutdown, both regulators completely disconnect the loads from the input supply to provide a true shutdown.
Other key safety features in the ADP5071 include overcurrent protection (OCP), overvoltage protection (OVP), thermal shutdown (TSD), and input undervoltage lockout (UVLO).
The ADP5071 is available in a 20-lead LFCSP or in a 20-lead TSSOP and is rated for a −40°C to +125°C junction temperature range.

The EVAL-AD5766SD2Z/EVAL-AD5767SD2Z are fully featured evaluation boards designed to easily evaluate all features of the AD5766/AD5767 16-channel, 16-bit/12-bit, voltage output digital-to-analog converters (DACs).
These evaluation boards integrate a power solution using the ADP5071. The ADP5071 switching regulator offers a power solution by generating a bipolar supply of 8 V and −22 V from a 3.3 V input to create a DAC voltage output range of −20 V to +6 V. Alternatively, supplying the DAC with a linear power supply via the on-board connector, J9, generates all ranges.
The on-board connector, via J10, or the EVAL-SDP-CB1Z system demonstration platform (SDP) board, via J1, can control the AD5766/AD5767. The SDP enables the control of evaluation boards through the USB port of a Windows® based PC using the AD5766/AD5767 the evaluation software, ACE.
The AD5766/AD5767 are 16-channel, 16-bit/12-bit, voltage output denseDAC® converters. The DACs generate output ranges from a 2.5 V reference. Output buffers permit the AD5766/AD5767 to source or sink up to 20 mA. The range is software selectable and any channel can be routed to the monitor pin for external monitoring. The integration of the reference and output buffers creates an easy to use universal solution.
The devices require four power supplies. AVDD and AVSS are the positive and negative high voltage power supplies, AVCC is the analog supply for the low voltage DAC circuitry, and a VLOGIC supply pin sets the logic levels for the digital interface pins.
The ACE software of the EVAL-AD5766SD2Z/EVAL-AD5767SD2Z has an intuitive graphic user interface (GUI) for the configuration of AD5766/AD5767 modes of operation through the synchronous serial port (SPORT) interface. Visit the ACE software page to view plug in modules for the evaluation boards and Circuits from the Lab® (CFTL) demo boards of many other Analog Devices devices.
Complete specifications for the AD5766/AD5767 are available in the AD5766/AD5767 data sheet, which must be consulted in conjunction with theuser guide (UG-1070) when using the EVAL-AD5766SD2Z/EVAL-AD5767SD2Z.
