NSA2300: General Sensor Conditioner with Digital Temperature Calibration NOVOSENSE DatasheetV2.1 Product Overview The NSA2300 is a highly integrated, low power high precision sensor conditioner for general resistive bridge sensors, which features a low noise instrument amplifier, a low power 24 bit Σ-Δ ADC, a digital sensor calibration DSP and a 12-bit DAC. The NSA2300 can provide an on-chip digital compensation of sensor offset, gain, temperature drift and non-linearity based on the internal fuse banks (OTP), which is fast, precise, without the cost overhead with trimming by laser or external components. Multiple temperature sensing methods are supported by NSA2300 for sensor’s temperature calibrating. Once calibrated, the pin VOUT can provide a selectable fixed level or ratio-metric analog output, and I2C, SPI and one wire (OWI) interfaces are supported for chip configuration, sensor calibrating and digital output. Key Features  Support both digital and analog output modes.  Input referred RMS noise: OSR=1024X, GAIN=32X 600nV @  OTP based digital calibration of sensor offset, sensitivity, temperature drift and non-linearity with a calibration precision up to 0.05% full scale.  1X~128X programmable gain for sensors with different input spans up to rail-to-rail.  Full set of diagnostic features  Low power instrument amplifier and 24-bit Σ-Δ ADC  Multiple temperature sensing methods  8-level resolution settings for conversion time and accuracy trade off  SPI / I2C serial interface  One Wire Interface (OWI) Supported  Ultra low power-down current ( < 0.2uA@25℃ )  Supply voltage 1.8V to 5.5V  Operation temperature from -40°C to 125°C Available Supports  Evaluation kit with calibration procedure for fast user design  Support for mass calibration  Quick circuit customization possible Applications  Pressure sensor conditioner  Magnetic sensor conditioner  Strain Gauge interface  Industry process control PDF
