Overview
The LTC2311IMSE-14#PBF, produced by Analog Devices Inc., is a high-performance 14-bit + sign successive approximation register (SAR) analog-to-digital converter (ADC). This device is designed for applications requiring high speed, low noise, and wide input common mode range. Operating from a single 3.3V or 5V supply, the LTC2311-14 is ideal for various high-speed applications due to its fast 5Msps throughput and one-cycle latency.
