NJU9103 Series
Analog Front End with High Gain PGA
-
Description
NJU9103 is a small size 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 single-ended input, differential input and pseudo-differential input.
NJU9103 can set the optimum gain to the pressure sensor, flow sensor by a wide range of gain setting. Sensor of the offset is corrected by internal D / A converter. Various parameters (such as gain, conversion rate, correction) settings can be easily set in the SPI communication from an external MCU.
NJU9103 will contribute to the customer's development time reduction and the series product release. NJU9103 is also can be mounted in a narrow application footprint by a small 8-pin package. Package is preparing the DFN and SSOP.Applications
- Pressure sensors
