  • Description

    NA2200 is a CMOS-based 5V AFE with up to 512 times internal PGA (Programmable Gain Amplifier). Internal 16-bit ΔΣ type A / D converter can perform conversion rates from 0.814ksps to 6.51ksps.The customer can choose internal A/D 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.
