The AD5382 is a 32-channel, 14-Bit DAC and is available in a 14 mm × 14 mm 100-lead LQFP package. It operates from a single 3 V or 5 V supply. Programmable gain (m) and offset (c) are provided per channel to facilitate system calibration. Each DAC channel is double-buffered which allows all DAC outputs to be updated simultaneously via an LDAC pin. Each channel has an on-chip output amplifier which allows rail-to-rail operation. The AD5382 includes an internal 1.25 V/2.5 V low-drift reference. The AD5382 contains a parallel interface with a WR pulse width of 20 ns, a 30 MHz SPI interface and a 400 kHz I2C-compatible interface.

Product Lifecycle Production
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Evaluation Kits (1)
The evaluation board allows the functionality and performance of the AD5382 to be easily evaluated. The evaluation board can be used as a stand alone board with control coming from an external DSP or micro-controller or it can be connected to a PC using the EVAL-SDP-CB1Z board. Software is provided which can be used to program the registers of the AD5382 via the SDP board. This device is pin-to-pin compatible with the AD5383 (32-ch 12-bit DAC).

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.
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.
