NSC2860X General Capacitive Sensor Conditioner Datasheet (EN) 1.0 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 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.  Ratio metric or absolute voltage output  PWM output  I2C, SPI, OWI output  64 Bytes EEPROM  Operation temperature: -40℃~125℃ Applications  Capacitive pressure sensors and transmitters Device Information Part Number NSC2860X Package QFN20 Functional Block Diagrams AVDD VDDHV Key Features  Integrated JEFT controller  C/V converter with at most ±16pF differential input  24-bit ADC for primary signal measurement  Low drift voltage reference  1x to 8x digital gain  16-bit DAC  Multiple filter settings VGATE Reference Driver VREFP DVDD Regulators RVP&OVP Bandgaps Calibration Registers Configuration Registers CINP 24-bit PADC C/V CINN Σ EXC OSC 64 bytes EEPROM I2C SPI OWI Filters & MCU 16-bit DAC EXCITATION OWI R11 R12 Output Driver R2 VTEMP VDD/2 Analog Output Module 24-bit TADC M UX SDO/DRYB CSB SCL SDA Control Logic CAPD AC  24-bit ADC for temperature measurement  Internal and external temperature sensor supported Body Size 4mm × 4mm OUT FBN R3 R4 LOOPN Temperature Sensor GND FILTER/HART NSC2860X Block Diagram  Built in sensor calibration logic  4～20mA output Copyright © 2022, NOVOSENSE Page 1  PDF
