HX711 24-Bit 2 Channel ADC Module with TL431 Chip

This module offers high precision with two analog channel inputs and an integrated 128x gain programmable amplifier inside. It uses the HX711, a 24-bit high-precision A/D converter chip designed for electronic weighing. The input circuitry can be configured to provide bridge voltage for bridge-type (e.g. pressure, weighing) transducer mode, making it an ideal high-precision, low-cost sampling front-end module.

The HX71124 high-precision ADC module with its own TL431 external voltage regulator uses an external voltage (2.5 V) as the excitation source for the external pressure sensor for higher voltage stability.
