ISL26321FBZ-T

Analog To Digital Converters (ADC) Overview

The ISL26321FBZ-T is a 12-bit, 250kSPS sampling Successive Approximation Register (SAR) Analog-to-Digital Converter manufactured by Renesas Electronics. It features an integrated input multiplexer and buffer amplifier to reduce external drive requirements. The device supports single-ended and differential inputs with pinout intercompatibility across the family. It operates on a supply voltage ranging from +2.7V to +5.25V and consumes 2.2mA typical operating current. Power-down current between conversions is typically 8µA. The component utilizes an SPI-compatible serial digital interface and offers high ESD survivability of 5kV HBM.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'FBZ-T' against official Renesas documentation to confirm tape-and-reel packaging and exact temperature grade. Ensure the source document explicitly lists this part number variant rather than generic family members. Cross-reference the manufacturer date code and lot traceability if required for your production line. Confirm RoHS compliance status as stated in the specific datasheet revision.

Analog To Digital Converters (ADC) Selection Notes

Select this component when designing systems requiring 12-bit resolution at 250kSPS with low power consumption. The integrated buffer simplifies analog front-end design by reducing drive requirements. Consider the pinout compatibility if upgrading from other members of the ISL2631x/ISL2632x family. Verify that the supply voltage range of 2.7V to 5.25V matches your system rails. Evaluate the ESD protection levels against your environmental exposure requirements.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ISL26310/11/12/13/14/15/19 and ISL26320/21/22/23/24/25/29 family of low-power ADCs. These parts share pinout intercompatibility, differing primarily in the number and type of analog inputs. The family is designed for applications requiring excellent linearity over supply and temperature variations. Members support quick replication of proven layouts across multiple design platforms due to their standardized interface and package options.

Analog To Digital Converters (ADC) Replacement Considerations

Other members of the ISL2632x family may serve as substitutes if input channel configurations differ but pinouts remain identical. Verify that any replacement maintains the 12-bit resolution and 250kSPS speed. Check for compatibility with the SPI interface protocol. Ensure the alternative part supports the same supply voltage range and industrial temperature specifications.
