EVAL-CN0254-SDPZ

EVAL-CN0254-SDPZ is a CN0254 circuit evaluation board. The circuit is a cost effective, highly integrated 16-bit, 250kSPS, 8-channel data acquisition system that can digitize ±10V industrial level signals. The system uses the AD7689 16-bit, 8-channel PulSAR ADC for high-resolution analogue-to-digital conversion, while the AD8608 and AD8605 precision rail-to-rail operational amplifiers provide accurate signal conditioning and buffering. The ADuM3471 PWM controller and transformer driver provide isolated power and support the isolation barrier between the measurement circuitry and host controller, with isolation of up to 2500Vrms. The ADP3336 500mA low-noise adjustable LDO is used to regulate the required supply voltage. The entire measurement circuit is powered from a single isolated PWM-controlled 5V supply, making the CN-0254 suitable for industrial data acquisition applications where signal accuracy, channel density, and electrical isolation are important.

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