Product Details

The EVAL-AD5770RSDZ is a fully featured evaluation board that is designed to help the user evaluate the AD5770R 6-channel, 14-bit, current output digital-to-analog converter (DAC).

The EVAL-AD5770RSDZ evaluation board is controlled by the following two methods: the on-board P11 connector and the EVAL-SDP-CB1Z (Connector P10). The system development (SDP-B) board uses the AD5770R evaluation software to control the EVAL-AD5770RSDZ evaluation board via a Windows^® PC USB port.

The EVAL-AD5770RSDZ board contains a power solution that uses the ADP5073 switching regulator to generate −2 V from a +3.3 V supply and the ADP1741 linear regulator to generate +2 V from a +3.3 V supply. Alternatively, the AD5770R also uses a linear power supply connected through the nine onboard connectors (P0 to P8). The AD5770R incorporates an internal 1.25 V precision reference. The EVAL-AD5770RSDZ board contains an additional 1.25, V 0.5 ppm/°C voltage reference.

The AD5770R evaluation software provides an intuitive graphic user interface (GUI) that configures and controls the AD5770R over the serial peripheral interface (SPI).

The AD5770R is a 6-channel, 14-bit resolution, low noise, programmable current output DAC for photonics control applications. The output current ranges are software selectable, and channels are routed to the MUX_OUT pin for external monitoring.

See the AD5770R data sheet for full details and consult the AD5770R data sheet in conjunction with the user guide when using the EVAL-AD5770RSDZ board.
