Introduction

AI Translation

The CS5532/34 are highly integrated ΔΣ Analog-to-Digital Converters (ADCs) which use charge-balance techniques to achieve 24-bit performance. The ADCs are optimized for measuring low-level unipolar or bipolar signals in weigh scale, process control, scientific, and medical applications. To accommodate these applications, the ADCs come as either two-channel (CS5532) or four-channel (CS5534) devices and include a very low-noise, chopper-stabilized instrumentation amplifier (6 nV/√Hz @ 0.1 Hz) with selectable gains of 1×, 2×, 4×, 8×, 16×, 32×, and 64×. These ADCs also include a fourth-order ΔΣ modulator followed by a digital filter which provides twenty selectable output word rates of 6.25, 7.5, 12.5, 15, 25, 30, 50, 60, 100, 120, 200, 240, 400, 480, 800, 960, 1600, 1920, 3200, and 3840 Sps (MCLK = 4.9152 MHz). To ease communication between the ADCs and a microcontroller, the converters include a simple three-wire serial interface which is SPI™ and Microwire™ compatible with a Schmitt-trigger input on the serial clock (SCLK). High dynamic range, programmable output rates, and flexible power supply options makes these ADCs ideal solutions for weigh scale and process control applications.
