ISL2671286IBZ

Analog To Digital Converters (ADC) Overview

The ISL2671286IBZ is a single-channel, 12-bit Analog-to-Digital Converter (ADC) manufactured by Renesas Electronics Corporation. It utilizes Successive Approximation Register (SAR) architecture with an integrated sample-and-hold circuit operating at a ratio of 1:1. The device supports a sampling rate of 20 kSPS and accepts differential input signals. It operates on a 5V supply for both analog and digital domains and features an external reference type. Data is transmitted via an SPI interface. The component is housed in an 8-SOIC package with a width of 3.90mm and functions within an operating temperature range of -40°C to 85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 12-bit SAR ADC with a dedicated sample-and-hold stage for accurate signal capture.
• Supports differential input configurations to enhance noise immunity in signal acquisition.
• Provides serial data output through a standard SPI-compatible interface for microcontroller connectivity.

Analog To Digital Converters (ADC) Applications

• Data acquisition systems requiring moderate speed and resolution
• Industrial process control monitoring
• Battery management system sensing

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IBZ' against the manufacturer's current datasheet to confirm pinout compatibility and packaging details. Ensure the external reference voltage requirements align with your system design, as this component does not include an internal reference. Confirm that the 5V supply rails match your board's power distribution network before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution is sufficient for the application. It is suitable for designs where a 20 kSPS sampling rate meets the bandwidth requirements. Consider the 8-SOIC package size constraints and the necessity for an external voltage reference source during the schematic design phase.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ISL267xx series of precision ADCs from Renesas (formerly Intersil). These devices are designed for general-purpose data conversion tasks, offering a balance between resolution and speed. The series typically includes variants with different sampling rates and resolutions, sharing similar architectural characteristics and interface protocols.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct cross-reference parts within the ISL267xx family or newer Renesas ADC portfolios. Verify pin-to-pin compatibility if substituting with other 8-SOIC SAR ADCs. Ensure the replacement supports differential inputs and SPI communication if those features are critical to the existing design.
