Overview
The LTC1272-8ACSW#TRPBF is a 12-bit, successive approximation analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is known for its high speed and accuracy, featuring a conversion time of 3µs and a sampling rate of 250kHz. It operates on a single 5V supply and is compatible with the industry-standard AD7572, although it requires adjustments for the reference capacitor polarity and sample-and-hold acquisition time. The LTC1272 uses LTBiCMOS™ switched-capacitor technology, combining a high-speed ADC with a fast and accurate sample-and-hold circuit and a precision reference.
