HX711 24-Bit Analog-to-Digital Converter (ADC) for Weigh Scales - (AD68832)

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 differential input B to a 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 the analog supply pin AVDD. Channel B has a fixed gain of 32. The on-chip power supply regulator eliminates the need for an external supply regulator to provide 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 which does not require any external component. The on-chip power-on-reset circuitry simplifies digital interface initialization. No programming is required for the internal register.

Note: This component has an SMD SOP-16 package
