The AD5390/AD5391 are complete single-supply， 16-channel， 14-bit and 12-bit DACs， respectively. The AD5392 is a complete single-supply， 8-channel， 14-bit DAC. The devices are available in either a 64-lead LFCSP or a 52-lead LQFP. All channels have an on-chip output amplifier with rail-to-rail operation. All devices include an internal 1.25/2.5 V， 10 ppm/°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. The AD5390/AD5391/AD5392 contain a 3-wire serial interface with interface speeds in excess of 30 MHz that are compatible with SPI?， QSPI?， MICROWIRE?， and DSP interface standards and an I2 C-compatible interface supporting a 400 kHz data transfer rate. An input register followed by a DAC register provides doublebuffering， 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. Power consumption is typically 0.25 mA per channel.
