Description

The AD5383 is a complete, single-supply, 32-channel, 12-bitdenseDAC®available in a 100-lead LQFP package. All 32 channels have an on-chip output amplifier with rail-to-rail operation. The AD5383 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 that allows optimization of the amplifier slew rate. The AD5383 features:Double-buffered parallel interface with a 20 nsWRpulse width.SPI-/QSPI-/MICROWIRE-/DSP-compatible serial interface with interface speeds in excess of 30 MHzI2C-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 theLDACinput.Each channel has a programmable gain and offset adjust register that allows the user to fully calibrate any DAC channel. With boost off, power consumption is typically 0.25 mA/channel.APPLICATIONSVariable optical attenuators (VOA)Level setting (ATE)Optical microelectro-mechanical systems (MEMS)Control systemsInstrumentation
