HX710B Weighing Scale 24-Bit Analog to Digital Convertor (ADC) IC DIP-8 Package

The HX710B is a precision 24-bit analog-to-digital converter (ADC) with built-in temperature sensor designed for weigh scales and industrial control applications to interface directly with a bridge sensor. The input low-noise amplifier (PGA) has a fixed gain of 128, corresponding to a full-scale differential input voltage of ?20mV, when a 5V reference voltage is connected to the VREF pin. On chip oscillator provides the system clock without any external component. On-chip power-on-reset circuitry simplifies digital interface initialization. There is no programming needed for the internal registers. All controls to the HX710B are through the pins.
