Description:

24-Bit Analog-to-Digital Converter

Features

* Selectable differential input or battery detection input
* On-chip low noise PGA with selectable gain of 128 and 256
* On-chip MOS power switch for turning off loadcell power supply in system power save mode
* On-chip oscillator requiring no external component with

Applications

* to interface directly with a bridge sensor. The differential inputs connect to the lownoise programmable gain amplifier (PGA) with a gain of 128 or 256, corresponding to a full-scale differential input voltage of ±20mV or ±10mV respectively, when a 5V reference voltage is connected between REFP and
