AD5370BSTZ Datasheet PDF - ADI

●The AD5370BSTZ is a 40-channel 16-bit Digital-to-analog Converter (DAC) provides buffered voltage outputs with a span that is 4x the reference voltage. The gain and offset of each DAC channel can be independently trimmed to remove errors. For even greater flexibility, the device is divided into five groups of eight DACs. Three offset DAC channels allow the output range of blocks to be adjusted. It offers guaranteed operation over a wide supply range, with VSS from -16.5 to -4.5V and VDD from 9 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 receipt 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 to allow removal of gain and offset er
