Overview
The ISL267450IUZ-T7A is a 12-bit, 1MSPS (Mega Samples Per Second) sampling SAR (Successive Approximation Register) 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 3V or 5V and maintains measurement accuracy with input signals up to the supply rails. The ADC features a simple SPI-compatible serial digital interface, making it easily interfaced with popular FPGAs and microcontrollers.
