Overview

The CS5521/22/23/24/28 family of highly integrated, Delta Sigma analog-to-digital (A/D) converters use charge-balance techniques to achieve 16-bit (CS5521/23) and 24-bit (CS5522/24/28) performance. The A/D converters come as either 2-channel (CS5521/22), 4-channel (CS5523/24), or 8-channel (CS5528) devices. They each include a low input current and chopper-stabilized, instrumentation amplifier. To permit selectable input spans of 25 mV, 55 mV, 100 mV, 1 V, 2.5 V and 5 V, the A/D converters include a PGA (programmable gain amplifier). To accommodate ground-based thermocouple applications, the devices include a charge pump drive, which provides a negative bias voltage to the on-chip amplifiers. These devices also include a fourth-order Delta Sigma modulator followed by a digital filter, which provides eight selectable-output word rates. The digital filters are designed to settle to full accuracy within one conversion cycle, and when operated at word rates below 30 Hz, they reject both 50 Hz and 60 Hz interference. These single-supply products are ideal solutions for measuring isolated and non-isolated, low-level signals in process-control applications.
