AD5371 40-Channel Voltage Output DACs
Analog Devices Inc. AD5371 40-Channel 14-bit Serial Input, Voltage Output DACs offer buffered voltage outputs with a range of four times the reference voltage. Each channel has a programmable gain and an offset adjust register. Designers can trim the gain and offset of each DAC independently to remove errors. For additional flexibility, the device is divided into five groups of eight DACs. Three offset DACs enable designers to adjust the output range of the groups. The AD5371 DACs provide guaranteed operation over a wide supply range, with VSS from -16.5V to -4.5V and VDD from 9V to 16.5V. The output amplifier headroom requirement is 1.4V operating with a load current of 1mA.
