ISL26102AVZ-T

Analog To Digital Converters (ADC) Overview

The ISL26102AVZ-T is a low-noise, 24-bit Analog-to-Digital Converter (ADC) from the ISL26102 series by Renesas Electronics. It features two differential channels with a Sigma-Delta architecture and supports sampling rates up to 4 kS/s. The device integrates an on-chip programmable gain amplifier (PGA) with gains ranging from 1 to 128. It operates with analog supply voltages between 4.75 V and 5.25 V, and digital supply voltages from 2.7 V to 5.25 V. The component utilizes a serial interface for communication and is housed in a TSSOP-24 package. It is specified for operation across an extended temperature range of -40°C to +105°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging rather than tube. Confirm the specific voltage variants and pinout compatibility with existing designs. Check for moisture sensitivity level requirements during storage and handling. Ensure the supplier provides valid traceability documentation for automotive-grade components.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring high precision with minimal external signal conditioning. Compare channel count against ISL26104 if four inputs are needed. Verify power consumption constraints against the 50mW active mode specification. Consider the integrated PGA range when designing for varying sensor output levels.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ISL26102/ISL26104 family of ultra-low noise ADCs introduced by Intersil, now part of Renesas. These devices are designed to simplify signal chains by integrating the PGA and ADC, reducing board space and component count compared to discrete solutions.

Analog To Digital Converters (ADC) Replacement Considerations

The ISL26102AVZ is the tube-packaged equivalent of this tape-and-reel variant. For multi-channel needs, the ISL26104 offers four differential inputs with similar specifications. Verify pin compatibility before substituting.
