AD5770RBCBZ-RL7

AD5770R is a 6-channel, 14bit resolution, low noise, programmable current output, digital-to-analogue converter (DAC) for photonics control applications. The device incorporates a 1.25V, on-chip voltage reference, a 2.5kohm precision resistor for reference current generation, die temperature, output monitoring functions, fault alarm, and reset functions. The AD5770R contains five 14bit resolution current sourcing DAC channels and one 14bit resolution current sourcing and sinking DAC channel. Channel 0 can be configured to sink up to 60mA and source up to 300mA. 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 0.8V to AVDD -0.4V for optimizing power efficiency and thermal power dissipation. Application includes photonics control, LED driver programmable current source, current mode biasing.
