This document describes the features of the CS5101A and CS5102A 16-bit, 100 kHz / 20 kHz A/D converters from Cirrus Logic, Inc. These converters have ultra-low distortion, fast conversion time, low linearity error, and self-calibration capabilities, making them suitable for battery-powered operation.
The document describes the CS5101A and CS5102A as 16-bit monolithic CMOS analog-to-digital (A/D) converters. These devices support throughput rates of 100 kHz for the CS5101A and 20 kHz for the CS5102A. They feature inherent sampling architecture, a two-channel input multiplexer, and flexible serial output ports with binary or 2's complement coding.
| Resolution | 16-bit |
|---|---|
| Linearity Error | ±0.001% FS |
| Total Harmonic Distortion (THD) | 0.001% |
| Signal-to-Noise Ratio | 92 dB |
| Conversion Time (CS5101A) | 8 µs |
| Conversion Time (CS5102A) | 40 µs |
| Power Consumption (CS5101A) | 320 mW |
| Power Consumption (CS5102A) | 44 mW |
The CS5101A supports a throughput rate of 100 kHz.
The power-down mode consumes less than 1 mW for both models.
