Evaluation Board for 14-/16-Bit, Serial Input, VOUT NanoDACsTM EVAL-AD5040EB/EVAL-AD506xEB
FEATURES
Full-featured evaluation board for the AD5040/AD506x Operates from single 2.7 V to 5.5 V supplies On-board reference Direct hookup to USB port of PC PC software for control of DAC Power-on reset to midscale or zero scale 3 power-down functions
The AD5040/AD506x devices offer a relative accuracy specification of 1 LSB and operation is guaranteed monotonic with a 1 LSB DNL specification. The AD5040 and AD506x devices use a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and are compatible with standard SPI , QSPITM, MICROWIRETM, and DSP interface standards. The reference for the AD5040 and AD506x devices is supplied from an external VREF pin. A reference buffer is also provided on-chip. The AD5040/AD506x incorporate a power-on reset circuit that ensures the DAC output powers up to midscale or zero scale and remains there until a valid write occurs. The AD5040 and the AD506x devices contain a power-down feature that reduces the current consumption of the device and provides software-selectable output loads while in power-down mode. The AD5061 is a low power, single 16-bit buffered voltage-out DAC. The AD5061 part offers a relative accuracy specification of 4 LSB, and operation is guaranteed monotonic with a 1 LSB DNL s
pecification. The AD5063 is a low power, single 16-bit buffered voltage-out DAC and comes with on-board resistors in a 10-lead MSOP, allowing bipolar signals to be generated with an output amplifier. The AD5062 is a low power, single 16-bit unbuffered voltage-out DAC. The AD5062 offers a relative accuracy specification of 1 LSB, and operation is guaranteed monotonic with a 1 LSB DNL specification. An external reference can also be applied via an SMB input connector. The evaluation board is powered via terminal blocks.

GENERAL DESCRIPTION
This data sheet describes the evaluation board for evaluating the AD5040, AD5060, AD5061, AD5062, and AD5063 nanoDACs. These devices are low power, single 14-/16-bit buffered voltage-out DACs. Operating from single 2.7 V to 5.5 V supplies, the devices are well suited to battery-powered and other applications.
