Avia semiconductor HX710
HX710 is a precision 24-bit analogto-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. All controls to the HX710 are through the pins.| Part No. | HX710 |
