Overview
The LTC2351IUH-14#TRPBF is a high-performance, 14-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed for simultaneous sampling of six differential input channels, making it ideal for applications requiring real-time monitoring of multiple signals. It operates at a sampling rate of 1.5 MS/s and features a successive approximation register (SAR) architecture. The ADC is packaged in a compact 32-pin QFN package, measuring 5mm x 5mm x 0.75mm, and is suitable for a wide range of applications due to its low power consumption and small form factor.
