Product Overview

The NSC2860X is an ASSP chip developed specifically for

industrial transmitters with 4~20mA current output,

0~5V voltage output or 0~10V voltage output. It is

designed to interface with capacitive pressure sensors

by integrating an internal capacitance-to-voltage

conversion circuit. It also provides a convenient OWI

interface for direct communication via analog output

line, allowing customers to easily calibrate and store

calibration coefficients after sensor assembly. In

addition, the NSC2860X also integrates a JFET

I2C, SPI, OWI output

64 Bytes EEPROM

Operation temperature: -40℃~125℃

Applications



Capacitive pressure sensors and transmitters

controller that can be used directly in standard

industrial loop power applications at 24V without the

need for an additional power supply controller. This

chip has been widely used in industrial capacitive

pressure transmitter applications over the past few

years, and its reliability and stability have been well

proven by large shipments in the industrial field.
