Product Overview

The EVAL-CN0312-SDPZ is a is a dual channel colorimeter circuit evaluation board that features a modulated light source transmitter and a synchronous detector receiver. This circuit evaluation board uses AD7798 16bit, sigma delta ADC with on chip in amp, AD8615/AD8618 operational amplifier, ADR4525 2.5V voltage reference, AD8271 programmable gain precision difference amplifier, ADG633 CMOS, ±5V/+5V/+3V, triple SPDT switch and ADG733 CMOS, 2.5ohm low voltage, triple SPDT switches. The circuit measures the ratio of light absorbed by the sample and reference containers at three different wavelengths. It provides an efficient solution for many chemical analysis and environmental monitoring instruments used to measure concentrations and characterize materials through absorption spectroscopy. Using the modulated source and synchronous detector rather than a constant (dc) source, eliminates measurement errors due to ambient light and low frequency noise and provides higher accuracy.
  • Dual channel RGB colorimeter
  • High sensitivity low noise transimpedance amplifier
  • Programmable gain TIA
