The AD5308 / AD5318 / AD5328 are octal 8-, 10-, and 12-bit buffered voltage output DACs in a 16-lead TSSOP. They operate from a single 2.5 V to 5.5 V supply, consuming 0.7 mA typical at 3 V. Their on-chip output amplifiers allow the outputs to swing rail-to-rail with a slew rate of 0.7 V/μs. The AD5308 / AD5318 / AD5328 use a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and is compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards.
The references for the eight DACs are derived from two reference pins (one per DAC quad). These reference inputs can be configured as buffered, unbuffered, or VDD inputs. The parts incorporate a power-on reset circuit, which ensures that the DAC outputs power up to 0 V and remain there until a valid write to the device takes place. The outputs of all DACs may be updated simultaneously using the asynchronous LDAC input. The parts contain a power-down feature that reduces the current consumption of the devices to 400 nA at 5 V (120 nA at 3 V). The eight channels of the DAC may be powered down individually.
All three parts are offered in the same pinout, which allows users to select the resolution appropriate for their application without redesigning their circuit board.

Evaluation Kits (1)
The AD5328DBZ evaluation board is designed to help users quickly prototype new AD5328 circuits and reduce design time. The AD5328 operates from a single 2.5 V to 5.5 V supply.
For full details, see the AD5328 data sheet, which must be used in conjunction with UG-978 when using the EVAL-AD5328DBZ evaluation board.
The evaluation board interfaces to the USB port of a PC via the SDP-B board. Software is available for download to allow the user to program the AD5328.
This evaluation board requires the EVAL-SDP-CB1Z board (SDP-B controller board), which is available for order on the Analog Devices website.
Features & Benefits
- Full featured evaluation board in conjunction with nanoDAC® motherboard (EVAL-MBnanoDAC-SDZ)
- On-board references
- Various link options
- PC control in conjunction with Analog Devices, Inc., system demonstration platform (SDP)

Tools & Simulations
Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
