- 2.5 V to 5.5 V power supply
- Double-buffered input logic
- Guaranteed monotonic by design over all codes
- Buffered/unbuffered reference input options
- See Data Sheet for Additional Information
The AD5330/AD5331/AD5340/AD5341 are single 8-/10-/12-bit DACs. They operate from a 2.5 V to 5.5 V supply consuming just 115 μA at 3 V and feature a power-down mode that further reduces the current to 80 nA. The devices incorporate an on-chip output buffer that can drive the output to both supply rails, but the AD5330, AD5340, and AD5341 allow a choice of buffered or unbuffered reference input.
The AD5330/AD5331/AD5340/AD5341 have a parallel interface. CS selects the device and data is loaded into the input registers on the rising edge of WR.
The GAIN pin allows the output range to be set at 0 V to VREF or 0 V to 2 × VREF.
Input data to the DACs is double-buffered, allowing simultaneous update of multiple DACs in a system using the LDAC pin.
An asynchronous CLR input is also provided, which resets the contents of the input register and the DAC register to all zeros. These devices also incorporate a power-on reset circuit that ensures that the DAC output powers on to 0 V and remains there until valid data is written to the device.
The AD5330/AD5331/AD5340/AD5341 are available in thin shrink small outline packages (TSSOP).

Evaluation Kits (1)
The AD5340DBZ evaluation board helps users quickly prototype new AD5340 circuits and reduce design time. The AD5340 operates from a single 2.5 V to 5.5 V supply.
For full data, see the AD5340 data sheet, which must be used in conjunction with UG-981 when using the evaluation board.
The EVAL-AD5340DBZ evaluation board interfaces to the USB port of a PC via the SDP-B board. Software is available for download that allows users to program the AD5340.
The EVAL-AD5340DBZ evaluation board requires the EVAL-SDP-CB1Z board (SDP-B controller board).
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)
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
