TC7109ACPL

TC7109ACPL Description

The TC7109ACPL from Microchip Technology is a high-precision 12-bit analog-to-digital converter (ADC) designed for applications demanding accurate signal conversion. Housed in a 40-DIP (Dual In-line Package), this ADC features a dual-slope architecture, ensuring exceptional noise immunity and linearity. It operates with a single 5V supply for both analog and digital sections, simplifying power management. The device supports differential input and requires an external reference voltage, offering flexibility in calibration. With a sampling rate of 30 samples per second, it is optimized for low-speed, high-accuracy measurements. Its parallel data interface enables straightforward integration with microcontrollers or logic circuits.
