CS5560-ISZR

Analog To Digital Converters (ADC) Overview

The CS5560-ISZR is a single-channel, 24-bit delta-sigma analog-to-digital converter (ADC) manufactured by Cirrus Logic. It supports a high-throughput conversion rate of 50 kSps with a conversion time of 20 µs. The device features fully differential analog inputs and on-chip buffers that provide high input impedance, reducing drive requirements for signal sources. It operates with an analog supply of +5V/GND or ±2.5V and a digital I/O supply ranging from +1.8V to +3.3V. Power consumption is specified at 85 mW with input buffers active and 70 mW with them off.

• Precision measurement equipment utilizing differential signals

Analog To Digital Converters (ADC) Procurement Notes

Verify the ISZR suffix indicates tape-and-reel packaging when sourcing components. Confirm the specific voltage configuration required for the application, as the device supports both +5V/GND and ±2.5V analog supplies. Ensure the digital interface voltage matches the system's 1.8V to 3.3V logic levels. Check current availability status as component lifecycles may vary.

Analog To Digital Converters (ADC) Selection Notes

Select the CS5560-ISZR for applications demanding high throughput without sacrificing 24-bit resolution. The integrated buffers make it suitable for sources with higher output impedance. Compare power consumption specifications against system constraints, noting the difference between buffer-on and buffer-off states. Ensure the SPI serial interface compatibility with the host processor.

Analog To Digital Converters (ADC) Part Context

The CS5560 belongs to Cirrus Logic's family of high-throughput delta-sigma ADCs. The ISZR designation specifically identifies the reel-packaged version of the chip, distinct from bulk-packaged variants like the ISZ. This part is often evaluated using platforms such as the CDB5560 evaluation board to assess performance in data capture systems.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same high-throughput family include the CS5560-ISZ. For systems requiring different channel counts or pinouts, other models in the CS55xx series may require schematic and software modifications.
