AD5382 datasheet

Description :

The AD5382 is a complete, single-supply, 32-channel, 14-bit denseDAC® available in a 100-lead LQFP package. All 32 channels have an on-chip output amplifier with rail-to-rail operation. The AD5382 includes an internal software-selectable 1.25 V/2.5 V,10 ppm/°C reference, an on-chip channel monitor function tha multiplexes the analog outputs to a common MON_OUT pin or external monitoring, and an output amplifier boost mode hat allows optimization of the amplifier slew rate. The AD5382 contains a double-buffered parallel interface, which features a 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 channel. Power consumption is typically 0.25 mA per channel when operating with boost mode disabled.
