Overview
The LTC2308IUF#PBF is a high-performance, 12-bit, 8-channel successive-approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This ADC operates at a sampling rate of up to 500 kilosamples per second (ksps) and is known for its low noise, low power consumption, and compact package. It features a flexible SPI/MICROWIRE compatible serial interface and includes an internal reference and a fully differential sample-and-hold circuit to reduce common-mode noise.
