The AD5380 is a complete single-supply, 40-channel, 14-bit DAC available in a 100-lead LQFP package. All 40 channels have an on-chip output that operates rail-to-railamplifier。 The device contains a programmable 1.25 V/2.5 V, 10 ppm/°C reference; On-chip channel monitoring multiplexes analog outputs to a common MON_OUT pin for external monitoring; Output amplifier boost mode optimizes amplifier slew rate. The AD5380 contains a double-buffered parallel interface with a WR pulse width of 20 ns, an SPI/QSPI/MICROWIRE/DSP-compatible serial interface with interface speeds greater than 30 MHz, and an I interface that supports 400 kHz data transfer rates2C-compatible interface.
The input registers and subsequent DAC registers provide double buffering, allowing the DAC outputs to be updated independently or simultaneously using the LDAC inputs.
Each channel has programmable gain and offset adjustment registers, allowing the user to fully calibrate any DAC channel. With boost mode disabled, typical power consumption is 0.25 mA per channel.
