Description
Description:-
HX711 24-Bit ADC IC ? SOIC16 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.
Channel B has a fixed gain of 32.
An on-chip power supply regulator eliminates the need for an external supply regulator to provide analog power for the ADC and the sensor.
The clock input is flexible.
It can be from an external clock source, a crystal, or the on-chip oscillator that does not require any external component.
On-chip power-on-reset circuitry simplifies digital interface initialization.
