Description

The AD5372 contain 32 16-/14-bit DACs in 64-lead LQFP and LFCSP packages. The devices provide buffered voltage outputs with a nominal 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 four groups of eight DACs. Two offset DACs allow the output range of the groups to be altered. Group 0 can be adjusted by Offset DAC 0, and Group 1 to group 3 can be adjusted by Offset DAC 1. The AD5372/AD5373 offer guaranteed operation over a wide supply range: VSSfrom −16.5 V to −4.5 V and VDD from 9 V to 16.5 V. The output amplifier headroom requirement is 1.4 Voperating with a load current of 1 mA.
