AD5381:  40-Channel 12-Bit 3 V/5 V Single-Supply Voltage-Output DAC

The AD5381 is a 40-channel, 12-Bit DAC and is available in a 14 mm x 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. ...More

AD5381:  40-Channel 12-Bit 3 V/5 V Single-Supply Voltage-Output DAC

Product Description

The AD5381 is a 40-channel, 12-Bit DAC and is available in a 14 mm x 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 AD5381 includes an internal 1.25 V/2.5 V low-drift reference. The AD5381 contains a parallel interface with a WR pulsewidth 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 AD5382 (32-ch 14-bit DAC) and the AD5383 (32-ch 12-bit DAC).
