The AD5390/AD5391 are complete 16-channel, 14-bit, and 12-bit DACs that operate from a single supply. The AD5392 is a complete single-supply, 8-channel, 14-bit DAC. Available in 64-pin LFCSP or 52-pin LQFP packages. All channels have a rail-to-rail in-chip output amplifier. All devices have a built-in 1.25 V/2.5 V 10 ppm/°C reference source. The on-chip channel monitoring function multiplexes the analog output to a common MON_OUT pin for external monitoring, and the output amplifier boost mode optimizes the output amplifier slew rate.
The AD5390/AD5391/AD5392 have a built-in three-wire serial interface with interface speeds of over 30 MHz and are compatible with SPI®, QSPI™, MICROWIRE™, and DSP interface standards; and an I2C-compatible interface that supports 400 kHz data transfer rates.
The input registers and rear DAC registers provide dual buffering, allowing the DAC outputs to be updated independently or simultaneously using the LDAC inputs. Each channel has programmable gain and offset adjustment registers that allow users to fully calibrate any DAC channel.
Typical power consumption per channel is 0.25 mA.
