24-Bit ADC with Built-in Temperature Sensor HX710B SOP-8

Beschrijving

Source: Low pressure sensor

Based on Avia Semiconductor’s patented
technology, 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.
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.
