HX710B DIP 24-Bit ADC

HX710(A/B) is a precision 24-bit analog-to-digital converter (ADC) with built-in temperature sensor (HX710A) or DVDD, AVDD voltage difference detection (HX710B). It’s 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 poweron-reset circuitry simplifies digital interface initialization. There is no programming needed for the internal registers. All controls to the HX710 are through the pins.
