SIC4343

Voltage Sensor Interface Chip

DOWNLOAD FACTSHEET

SIC4343 is a 236-byte NFC tag IC with voltage sensor analog front-end. The SIC4343 consists of an RF Analog-Front-End circuit supporting
ISO/IEC 14443 A, a selectable 6-to-16-bit resolution sigma-delta ADC, an on-chip regulator, two 8-bit DACs, a voltage reference, a digital controller
and an EEPROM. SIC4343 is designed to perform voltage biasing and voltage measurement across sensor.

Highlight Features

Built-In ADC
- Selectable Post Processing Average
- Adjustable Conversion Starting Point to Avoid
Uplink to Ensure Power Stability
- Configurable Built-In Voltage Buffer for High-Impedance Sensor
Adjustable Sensor Biasing Frequency for Supporting Wide Capacitance-Range Sensor
Adjustable Sampling Point and Warm Up Clock
Support High Input impedance configuration
