AD5391BSTZ-5 Datasheet PDF - ADI

The AD5391BSTZ-5 is a complete single-supply 16-channel 12-bit Digital-to-Analog (DAC) contain a 3-wire serial interface with interface speeds in excess of 30MHz that are compatible with SPI®, QSPI™, MICROWIRE™ and DSP interface standards and an I²C-compatible interface supporting a 400kHz data transfer rate. All channels have an on-chip output amplifier with rail-to-rail operation. The device includes an internal 1.25/2.5V, 10ppm/°C reference, an on-chip channel monitor function that multiplexes the analog outputs to a common MON_OUT pin for external monitoring and an output amplifier boost mode that optimizes the output amplifier slew rate. An input register followed by a DAC register provides double-buffering, allowing DAC outputs to be updated independently or simultaneously using the LDAC input. Each channel has a programmable gain and offset adjust register, letting the user fully calibrate any DAC channel.
