Product Details

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 kΩ 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.
