CS5373A Overview
The CS5373A is a high-performance, fourth-order ∆Σ modulator integrated with a ∆Σ digital-to-analog converter (DAC). When bined with a CS3301A / CS3302A differential amplifier and the CS5378 digital filter, a small, low-power, self-testing, high-accuracy, singlechannel measurement system results. The modulator has high dynamic range and low total harmonic distortion with very low power consumption.
