The AD5382 is a 32-channel, 14-bit DAC and is available in a 14mm x 14mm 100-lead LQFP package. It operates from a single 3V or 5V supply. Programmable gain (m) and offset (c) are provided per channel to facilitate system calibration. Each DAC channel is double-buffered which allows all DAC outputs to be updated simultaneously via an LDAC pin. Each channel has an on-chip output amplifier which allows rail-to-rail operation. The AD5382 includes an internal 1.25V/2.5V low-drift reference. The AD5382 contains a parallel interface with a WR pulse width of 20ns, a 30MHz SPI interface and a 400 kHz I2C-compatible interface.
