HX712 Datasheet | AVIA Semiconductor

24-Bit Analog-to-Digital Converter (ADC) with Load-cell Power Supply Switch and Battery Voltage Detection for Weigh Scales DESCRIPTION Based on Avia Semiconductor’s patented technology, HX712 is a precision 24-bit analogto-digital converter (ADC) with on chip load-cell power supply switch and battery voltage detection. It’s designed for weigh scales and industrial control applications to interface directly with a bridge sensor. The differential inputs connect to the lownoise programmable gain amplifier (PGA) with a gain of 128 or 256, corresponding to a full-scale differential input voltage of ±20mV or ±10mV respectively, when a 5V reference voltage is connected between REFP and...
