Overview
The ISL26708IRTZ-T7A, produced by Renesas Electronics America Inc., is an 8-bit, 1MSPS (Mega Samples Per Second) SAR (Successive Approximation Register) type Analog-to-Digital Converter (ADC). This component is part of the ISL26712, ISL26710, and ISL26708 family, which features excellent linearity over supply and temperature variations. The ADC offers a robust, fully-differential input with high impedance to minimize errors due to leakage currents, ensuring accurate measurements even with input signals up to the supply rails.
The device is designed for flexibility, accepting reference inputs from 0.1V to 2.2V for 3V operation and 0.1V to 3.5V for 5V operation. It also features up to 8kV Human Body Model ESD survivability and a simple SPI-compatible serial digital interface, making it easy to interface with popular FPGAs and microcontrollers.
