AD5371 datasheet

Description :

GENERAL DESCRIPTION
The AD5371 contains 40 14-bit DACs in a single 80-lead LQFP or 100-ball CSP_BGA. The device provides buffered voltage outputs with a span of 4× the reference voltage. The gain and offset of each DAC can be independently trimmed to remove errors. For even greater flexibility, the device is divided into five groups of eight DACs. Three offset DACs allow the output range of the groups to be adjusted. Group 0 can be adjusted by Offset DAC 0, Group 1 can be adjusted by Offset DAC 1, and Group 2 to Group 4 can be adjusted by Offset DAC 2. The AD5371 offers guaranteed operation over a wide supply range, with VSSfrom −16.5 V to −4.5 V and VDDfrom 9 V to 16.5 V. The output amplifier headroom requirement is 1.4 V operating with a load current of 1 mA.
