Analog Front End with 24-bit 4ksps ADC for Medical, seismic business & weighing scale is a 24-bit delta sigma analog-to-digital converter (ADC) containing a low noise programmable gain amplifier (PGA) with a programmable update rate. This ADC is very well suited for low power applications further enhancing its battery life by introducing the bridge sensor to switch off when not converting. This ADC operates with a power supply from 2.7 V to 5.5 V.
