The AD5382 is a 32-channel, 14-bit DAC available in a 14 mm × 14 mm, 100-lead LQFP package. It operates from a single 3 V or 5 V supply and provides programmable gain (m) and offset (c) per channel for easy system calibration. Each DAC channel is doublebuffered, allowing all DAC outputs to be updated simultaneously through the LDAC pin. Each channel has an on-chip output capable of rail-to-rail operationamplifier。 The AD5382 contains a low drift reference of 1.25 V/2.5 V. It includes a parallel interface with a WR pulse width of 20 ns, a 30 MHz SPI interface, and a 400 kHz I2C-compatible interface.
This device is associated with the AD5380 (40-channel, 14-bit DAC), AD5381 (40-channel, 12-bit DAC), and AD5383 (32-channel, 12-bit DAC) pin compatible.
