Product Introduction

Overview

The ISL267450IBZ is a 12-bit, 1MSPS (Mega Samples Per Second) Successive Approximation Register (SAR) type Analog-to-Digital Converter (ADC) produced by Renesas Electronics America Inc. This device is known for its excellent linearity over supply and temperature variations and is drop-in compatible with the AD7450. It operates from a supply voltage of either 5V or 3V and maintains measurement accuracy with input signals up to the supply rails. The ISL267450IBZ features a serial digital interface that is SPI compatible, making it easily interfaced with popular FPGAs and microcontrollers.
