Analog Devices Inc.

The AD5770R is a 6-channel, 14-bit resolution, low noise, programmable current output, digital-to-analog converter (DAC) for photonics control applications. The device incorporates a 1.25 V, on-chip voltage reference, a 2.5 k? precision resistor for reference current generation, die temperature, output monitoring functions, fault alarm, and reset functions.The AD5770R contains five 14-bit resolution current sourcing DAC channels and one 14-bit resolution current sourcing and sinking DAC channel.Channel 0 can be configured to sink up to 60 mA and source up to 300 mA. Channel 1 to Channel 5 have multiple programmable output current sourcing ranges set by register access.Each DAC operates with a wide power supply rail from 0.8 V to AVDD ? 0.4 V for optimizing power efficiency and thermal power dissipation.The AD5770R operates from a 2.9 V to 5.5 V AVDD supply and is specified over the ?40?C to +105?C temperature range.ApplicationsPhotonics controlLED driver programmable current sourceCurrent mode biasing
