An Analog-to-Digital Converter (ADC) is an electronic device or circuit that converts analog signals into digital representations. In other words, it takes continuous analog signals and converts them into discrete digital values that can be processed by digital systems like microcontrollers, computers, or digital signal processors (DSPs).

Description
Based on Avia Semiconductor’s patented technology, HX711 is a precision 24-bit analog-to-digital converter (ADC) designed for weigh scales and industrial control applications to interface directly with a bridge sensor.
The input multiplexer selects either Channel A or B differential input to the low-noise
programmable gain amplifier (PGA). Channel A can be programmed with a gain of 128 or 64,
corresponding to a full-scale differential input voltage of ±20mV or ±40mV respectively, when
a 5V supply is connected to AVDD analog power supply pin.
Features
• Two selectable differential input channels
• On-chip active low noise PGA with selectable gain of 32, 64 and 128
• On-chip power supply regulator for load-cell and ADC analog power supply
• On-chip oscillator requiring no external component with optional external crystal
• On-chip power-on-reset
Pinouts:
Applications:
• Weigh Scales
• Industrial Process Control
