The AD5372/AD5373 contain 32, 16-bit or 14-bit digital-to-analog converters (DACs) in a single 64-lead LQFP. The devices provide buffered voltage outputs with a nominal span of 4× the reference voltage. The gain and offset of each DAC can be inde-pendently 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: VSS from −16.5 V to −4.5 V and VDD from 9 V to 16.5 V. The output amplifier headroom requirement is 1.4 V operating with a load current of 1 mA.
The ADAD5372/AD5373 have a high-speed serial inter- face, which is compatible with SPI, QSPI™, MICROWIRE™, and DSP interface standards and can handle clock speeds of up to 50 MHz.
The DAC registers are updated on reception of new data. All the outputs can be updated simultaneously by taking the LDAC input low. Each channel has a programmable gain and an offset adjust register.
Each DAC output is gained and buffered on-chip with respect to an external SIGGNDx input. The DAC outputs can also be switched to SIGGNDx via the CLR pin.
