AD5373BSTZ

AD5373BSTZ contains 32 14bit DACs. This device provides 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. It offers guaranteed operation over a wide supply range: 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. It has a high-speed serial interface that is compatible with SPI, QSPI™, MICROWIRE™, and DSP interface standards and can handle clock speeds of up to 50MHz. The DAC registers are updated on the 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. Applications include level setting in automatic test equipment (ATE), variable optical attenuators (VOA), optical switches, industrial control systems, and instrumentation.
