ISL26104AVZ

Analog To Digital Converters (ADC) Overview

The ISL26104AVZ is a low-noise, 24-bit Analog-to-Digital Converter (ADC) from the ISL2610x series by Renesas Electronics. It integrates a programmable gain amplifier with four differential, multiplexed inputs. The device supports conversion rates ranging from 2.5 Sps to 4 kSps and offers programmable gains from 1 to 128. It utilizes a Sigma-Delta architecture with a 3rd-order modulator, providing up to 21.5 bits of noise-free performance at 10 Sps. Power supplies include an analog voltage range of 4.75 V to 5.25 V and a digital range of 2.7 V to 5.25 V. It operates within a temperature range of -40°C to +105°C and uses a serial interface.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified suppliers. Check for moisture sensitivity labeling and ensure proper handling procedures are followed during storage and assembly. Confirm that the specific suffix matches the required package and temperature grade specifications before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this model when four independent differential channels are required alongside integrated amplification. Ensure the system design accommodates the specified dual power supply rails. Verify that the serial interface timing aligns with the host microcontroller capabilities. Consider the thermal operating limits if deployed in enclosed industrial environments.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ISL2610x family of precision ADCs, which also includes the two-channel ISL26102 variant. The series is designed for applications needing high accuracy and low noise. Renesas acquired Intersil, under which this part was originally developed, maintaining continuity in the product line's technical specifications and support documentation.

Analog To Digital Converters (ADC) Replacement Considerations

The ISL26102AVZ serves as a functional substitute if only two differential channels are sufficient for the application. Both parts share identical electrical characteristics, pinouts, and software compatibility. No hardware modifications are required when switching between these variants within the same design constraints.
