Overview
The LTC1411CG#PBF is a 14-bit, 2.5 Msps (Mega Samples Per Second) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is housed in a 36-lead plastic SSOP (Shrink Small Outline Package) and operates from a single 5V supply, dissipating only 195mW. It features a high-bandwidth sample-and-hold circuit, a precision reference, and an internally trimmed clock. The ADC supports both differential and single-ended inputs and presents data in 2’s complement format. It is designed for low power applications with Nap and Sleep modes and offers outstanding dynamic performance, including 80dB S/(N + D) and 90dB THD at 100kHz input frequency.
