The AD5305/AD5315/AD5325 are quad 8-, 10-and 12-bit buffered voltage output DACs in a 10-lead microSOIC package that operate from a single 2.5 V to 5.5 V supply consuming 500 µA at 3 V. Their on-chip output amplifiers allow rail-to-rail output swing with a slew rate of 0.7 V/µs. A 2-wire serial inter- face is used which operates at clock rates up to 400 kHz. This interface is SMBus-compatible at VDD <3.6 V. Multiple devices can be placed on the same bus.
- Available in a 10-lead MicroSOIC package
- Low power, single supply operation from 2.5 V to 5.5 V supply
- Consumes 1.5mW at 3 V and 3 mW at 5 V
- Rail-to-Rail output with a slew rate of 0.7 V/µs
- Multiple devices can share the same bus
- Reference derived from the power supply
- Serial interface with clock rates up to 400 kHz
- Pin- and Software-Compatible with the AD5305 (8-Bit) and the AD5315 (10-Bit)

Evaluation Kits (1)
The AD5325 evaluation board is designed to help users quickly prototype new AD5325 circuits and reduce design time. The AD5325 operates from a single 2.5 V to 5.5 V supply.
Full details are available in the AD5325 data sheet, which must be consulted in conjunction with UG-976 when using the evaluation board.
The evaluation board interfaces to the USB port of a PC via the SDP-B board (EVAL-SDP-CB1Z). Software is supplied with the evaluation board to allow the user to program the AD5325.
This evaluation board requires the SDP-B board (EVAL-SDP-CB1Z).
