ISL2671286IBZ-T

Analog To Digital Converters (ADC) Overview

The ISL2671286IBZ-T 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 single 5V supply for both analog and digital domains. Data is transmitted via an SPI interface, and the component requires an external voltage reference. It is housed in an 8-SOIC package with a width of 3.90 mm 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.
• Operates from a single 5V power supply, simplifying power distribution requirements.

Analog To Digital Converters (ADC) Applications

• Data acquisition systems requiring moderate speed and resolution.
• Industrial process control monitoring.
• Battery-powered instrumentation with single-supply constraints.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IBZ-T against official Renesas documentation to confirm the tape and reel packaging format and industrial temperature grade. Ensure the external reference voltage source matches the required accuracy for the 12-bit performance specification. Confirm that the SPI timing parameters align with the host controller's capabilities before finalizing the procurement order.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution is sufficient for the application. The 20 kSPS sampling rate suits low-frequency signal monitoring tasks. Consider the external reference requirement if system cost or board space is constrained. Verify that the 8-SOIC package dimensions fit the available PCB footprint and that the differential input capability is utilized for the specific sensor interface.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Intersil/Renesas portfolio of mixed-signal conversion devices. The ISL26712 series typically offers various resolutions and speeds. The IBZ-T designation indicates the specific package style and bulk packaging method. This component serves as a bridge between analog sensor outputs and digital processing units in embedded systems.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-compatible alternatives within the ISL267xx family that may offer different sampling rates or resolutions. Verify that any substitute maintains the same 5V supply requirement and SPI interface compatibility. Ensure the replacement part supports differential inputs if that feature is critical to the design.
