HX710A 24bit ADC with Built-in Temperature Sensor SMD SOP8

Description

DESCRIPTION: Based on Avia Semiconductor’s patented technology, HX710A is a precision 24-bit analog-to-digital converter (ADC) with built-in temperature sensor (HX710A) . 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 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. FEATURES: • On-chip temperature measurement (HX701A) • On-chip low noise amplifier with a gain of 128 • On-chip oscillator requiring no external component • On-chip power-on-reset • Simple digital control and serial interface: pin-driven controls, no programming needed • Selectable 10SPS or 40SPS output data rate • Simultaneous 50 and 60Hz supply rejection • Current consumption: normal operation < 1.2mA, power down < 1uA • Operation supply voltage range: 2.6 ~ 5.5V • Operation temperature range: -40 ~ +85℃ • 8 pin SOP-8 package Datasheet
