ISL267450IUZ-T

Analog To Digital Converters (ADC) Overview

The ISL267450IUZ-T is a 12-bit, 1MSPS successive approximation register (SAR) analog-to-digital converter manufactured by Renesas Electronics. It features a robust, fully-differential input with high impedance to minimize leakage current errors and maintains specified measurement accuracy with input signals up to the supply rails. The device operates with reference inputs from 0.1V to 2.2V for 3V systems or 0.1V to 3.5V for 5V systems. Power consumption is 8.5mW at 1MSPS and drops to 5µW in Auto Power-Down mode with a 5V supply. It utilizes an SPI-compatible serial digital interface and is housed in an 8-lead MSOP package, specified for operation over the industrial temperature range of –40 °C to +85 °C.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized channels as this part number is listed as End-of-Life (EOL). Confirm that the specific suffix matches the required package and tape/reel specifications. Check for valid RoHS compliance documentation before integration into new designs due to discontinuation status.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 1MSPS sampling rate are required within a compact 8-lead MSOP footprint. Ensure the design supports the specified reference voltage ranges for the target supply rail. Consider the low power dissipation characteristics for battery-powered applications requiring auto power-down functionality.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ISL267450 series of SAR ADCs, which includes the 10-bit ISL267440 variant.
