The AD5392 is complete single-supply, 8-channel, 14-bit DACs, respectively. 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 converter 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 I2C-compatible interface supporting a 400 kHz data transfer 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.
