NJU9103V-TE1

Analog Front End (AFE) Overview

The NJU9103V-TE1 is a high-gain Analog Front End (AFE) featuring a 16-bit Delta-Sigma ADC and dual Programmable Gain Amplifiers (PGA). It supports a supply voltage range of +2.7V to +3.6V and operates within an ambient temperature range of -40°C to +125°C. The device offers data rates from 0.814ksps to 6.51ksps with SPI interface control. PGA gain settings span from 1V/V to 512V/V, enabling precise signal conditioning for low-level sensor outputs.

Analog Front End (AFE) Feature Summary

• Integrated 16-bit ADC with no missing codes and data rates up to 6.51ksps
• Dual PGA architecture providing total gain from 1V/V to 512V/V
• Internal system calibration capabilities for offset and gain drift correction
• Supports differential, single-ended, and pseudo-differential input modes

Analog Front End (AFE) Applications

• Pressure sensors
• Flowmeters
• PLC systems
• Digital Panel Meters
• Thermostats

Analog Front End (AFE) Procurement Notes

Verify the specific package variant during ordering. The NJU9103V designation corresponds to the SSOP-8 package, while the NJU9103KV1 variant utilizes the DFN8 package. Confirm that the TE1 suffix aligns with the required taping form for the SSOP-8 version to ensure compatibility with assembly equipment.

Analog Front End (AFE) Selection Notes

Select this component when applications require high gain amplification combined with digitization in a compact footprint. The SSOP-8 package is suitable for standard surface mount processes. Ensure the external reference voltage matches the VREF pin requirements, typically set to 0.5 x VDD for optimal performance.

Analog Front End (AFE) Part Context

This part belongs to the NJU9103 series of analog front ends designed for industrial sensor interfaces. The NJU9103V-TE1 specifically denotes the SSOP-8 package configuration. Other variants in the family include the NJU9103KV1, which features a smaller DFN8 outline, allowing designers to choose based on board space constraints.

Analog Front End (AFE) Replacement Considerations

The NJU9103KV1 serves as a package-compatible alternative offering the same electrical specifications in a DFN8 outline. Designers must adjust PCB footprints accordingly when substituting between the SSOP-8 and DFN8 versions.
