HX710B-24Bit Analog To Digital Converters(ADC) SOP8

Description

GENERAL DESCRIPTION

Based on Avia Semiconductor’s patented technology, HX710 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 HX710 are through the pins.
