Galvanostat Sensor Interface Chip

DOWNLOAD FACTSHEET

SIC4340 is a 236-byte NFC tag IC for resistive/capacitive sensor interface which can apply for chemical sensor, light sensor etc. The SIC4340 consists of an NFC Analog-Front-End circuit supporting ISO/IEC 14443 A, a selectable 5-to-10 bit resolution sigma-delta ADC, an on-chip regulator, a sensor interface circuit, a temperature compensate voltage reference, a control register page and an EEPROM. The SIC4340 is designed to get sensor’s voltage response at specific time after biasing. The sensor can be resistive, capacitive or combination of them.
