Description

NA2200 is a CMOS-based 5V AFE with up to 512 times internal PGA (Programmable Gain Amplifier). Internal 16-bit ΔΣ type Analog to Digital converter (ADC) can perform conversion rates from 0.814ksps to 6.51ksps. The customer can choose internal Analog to Digital converter’s input, among differential input, single-ended input and pseudo-differential input. NA2200 can set the optimum gain to the pressure sensor, flow sensor by a wide range of gain setting. Various parameters (such as gain, conversion rate, correction) settings can be easily set in the SPI communication from an external MCU.

Applications

  • Pressure sensors
  • Flowmeters
  • Current Measurement
  • Thermostat
