Product Details

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.

This device is pin-to-pin compatible with the AD5380 (40-ch 14-bit DAC), the AD5381 (40-ch 12-bit DAC) and 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.
