HX712 - 24-Bit Analog-to-Digital Converter

General 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.

Key Features

  • Selectable differential input or battery detection input.
  • On-chip low noise PGA with selectable gain of 128 and 256.
  • On-chip MOS power switch for turning off loadcell power supply in system power save mode.
  • On-chip oscillator requiring no external component with optional external crystal.
  • On-chip power-on-reset.
  • Simple digital control and serial interface: pin-driven controls, no programming needed.
  • Selectable 10SPS or 40SPS output.

HX712 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 REFN pins. Singleended battery detection input pin BAT can be connected directly to battery output.
