EVAL-CN0348-SDPZ

EVAL-CN0348-SDPZ is a CN0348 circuit evaluation board. The circuit is a complete single-supply, 16-bit buffered voltage output DAC that maintains ±1 LSB integral and differential nonlinearity by utilizing a CMOS DAC followed by an innovative amplifier that has no crossover distortion. The circuit eliminates the crossover nonlinearity associated with most rail-to-rail op amps that can be as high as 4 or 5 LSBs for a 16-bit system. This industry-leading solution is ideal for industrial process control and instrumentation applications where a compact, single-supply, low cost, and highly linear 16-bit buffered voltage source is required. Total power dissipation for the three active devices is less than 25mW typical when operating on a single 6V supply. It uses an It uses an AD5541A serial-input, unbuffered 16-bit DAC, an ADA4500-2 rail-to-rail input/output operational amplifier with zero-crossover distortion, and an ADR4550 ultralow-noise, high-accuracy 5V voltage reference.

• Evaluation board connects to SDP-B controller board (EVAL-SDP-CB1Z) through 120-pin connector
