NSA2860: General Sensor Conditioner NOVOSENSE Datasheet (EN) 1.3  4～20mA current loop Product Overview The NSA2860 is a highly integrated IC for sensor conditioning and transmitting. It can be used for resistive or voltage output sensors like resistive bridge pressure sensor, thermocouple, RTD etc. The NSA2860 integrates an external JFET regulator, a 24-bit primary signal measurement channel, a 24-bit temperature measurement channel, sensor calibration logic, a pair of constant current sources and a 16-bit DAC. It can provide digital, 0~5V, 0~10V, 4~20mA, PWM and PDM outputs. The high integrity enables very compact PCB design with very few external components. With the internal calibration algorithm built in the MCU, the NSA2860 supports to compensate the temperature drift of zero and span up to the 2nd order and also the linearity up to the 3rd order.  Ratiometric or absolute voltage output  Special OWI communication  SPI/I2C  PWM/PDM  Others  High voltage regulator with external JFET or Bipolar  Package options: SSOP16 (30mm2) ， TSSOP20  AEC-Q100 qualified for SSOP16  Operation temperature: -40℃~150℃ Applications Key Features  Pressure sensors and transmitters  Analog Functions  Thermocouple transmitter  Low drift voltage reference  RTD temperature transmitter  Instrumental amplifier with variable gain from 1X to 256X  Other sensors  24-bit ADC for primary signal measurement  VGATE  Internal and external temperature sensor supported AVDD DVDD VREFP OWI  A pair of current sources GND  16-bit DAC VIP FBN Digital Functions VIN FILTER/HART  1X~8X digital gain IEXC1 LOOPN  Multiple filter settings IEXC2 TEMP  Sensor calibration logic with built-in MCU  EEPROM  VDDHV  24-bit ADC for temperature measurement Output Novosense Confidential Page 1 NSA2860_ QSSO16 OUT  PDF
