CS5571-ISZR

Analog To Digital Converters (ADC) Overview

The CS5571-ISZR is a single-channel, 16-bit delta-sigma analog-to-digital converter (ADC) from Cirrus Logic Inc., housed in a 24-SSOP surface-mount package. It supports a maximum conversion rate of 100 kSps using a 16 MHz master clock. The device accepts single-ended analog inputs and features on-chip buffers for high input impedance. Power supply configurations include ±2.375V to ±2.625V or +5V for analog supplies, with digital I/O operating at 1.8V to 3.3V. Key performance metrics include a linearity error of 0.0008%, a signal-to-noise ratio of 92 dB, and a differential non-linearity (DNL) of ±0.1 LSB maximum.

Analog To Digital Converters (ADC) Feature Summary

• High-throughput 16-bit resolution with 100 kSps sampling rate
• Single-ended analog input with integrated high-impedance buffers
• Low-latency digital filter architecture settling in one conversion cycle
• Flexible power supply options: ±2.5V or +5V analog; 1.8V–3.3V digital

Analog To Digital Converters (ADC) Applications

• High-speed data acquisition systems requiring fast settling times
• Multiplexed sensor interfaces where channel switching occurs without throughput loss
• Industrial process control applications utilizing single-ended signal sources

Analog To Digital Converters (ADC) Procurement Notes

Verify the ISZR suffix indicates tape-and-reel packaging when sourcing components. Confirm that the specific revision matches current design requirements, as datasheets may undergo updates. Ensure availability aligns with project timelines, noting that component status should be checked against official manufacturer channels for active production status.

Analog To Digital Converters (ADC) Selection Notes

Select the CS5571-ISZR when single-ended input compatibility and high speed are prioritized over differential noise rejection. Use this part if system architecture requires on-chip buffering to minimize source impedance effects. Ensure the application can provide a stable 16 MHz clock or utilize the internal oscillator if jitter tolerance permits DC measurements.

Analog To Digital Converters (ADC) Part Context

The CS5571 belongs to Cirrus Logic's family of high-throughput delta-sigma ADCs. Unlike lower-speed precision ADCs in the same portfolio, this model emphasizes speed and low latency. The ISZR variant specifically denotes the reel-packaged version of the standard ISZ through-hole or tube-part equivalent, facilitating automated assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family require verification of input type (single-ended vs. differential). Other Cirrus Logic models like the CS5581 offer similar architectures but may differ in channel count or specific electrical characteristics. Cross-reference datasheets for exact timing and supply voltage compatibility.
