AD5381:  40-Channel 3 V/5 V Single-Supply 12-Bit Voltage-Output DAC

Product Details

The AD5381 is a complete, single-supply, 40-channel, 12-Bit DAC available in a 100-lead LQFP package. All 40 channels have an on-chip output amplifier wiht rail-to-rail operarion. The AD5381 includes a programmable internal 1.25 V/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, which allows optimization of the amplifier slew rate. The AD5381 contains a double-buffered parallel interface featuring 20 ns WR pulse width, an SPI-/QSPI-/MICROWIRE-/DSP-compatible serial interface with interface speeds in excess of 30 MHz, and an I2C-compatible interface that supports a 400 kHz data transfer rate.

An input register followed by a DAC register provides double buffering, allowing the DAC outputs to be updated independently or simultaneously using the LDAC input.

Each channel has a programmable gain and offset adjust register that allows the user to fully calibrate any DAC chan-nel. Power consumption is typically 0.25 mA/channel with boost mode disabled.
