Description
General part information
AD5382 Series
The AD5382 is a 32-channel, 14-Bit DAC and is available in a 14 mm × 14 mm 100-lead LQFP package. It operates from a single 3 V or 5 V 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 anLDACpin. Each channel has an on-chip output amplifier which allows rail-to-rail operation. The AD5382 includes an internal 1.25 V/2.5 V low-drift reference. The AD5382 contains a parallel interface with aWRpulse width of 20 ns, a 30 MHz SPI interface and a 400 kHz I2C-compatible interface.This device is pin-to-pin compatible with theAD5380(40-ch 14-bit DAC), theAD5381(40-ch 12-bit DAC) and theAD5383(32-ch 12-bit DAC).APPLICATIONSVariable optical attenuators (VOAs)Level setting (ATE)Optical micro-electro-mechanical systems (MEMS)Control systemsInstrumentation
