Overview
The NJM2783V-TE1 is a monaural microphone amplifier with an auto level control (ALC) function, designed to prevent distortion from clipping. It operates on a supply voltage of +2.7V to +13.0V and features adjustable voltage gain (+20dB to +63dB) and limit levels via external resistors. The device includes a switchable additional gain amplifier (0dB/+20dB), a built-in buffer amplifier, and low equivalent input noise (1 µVrms typ.). Packaged in SSOP14, it utilizes bipolar technology and is optimized for mini component audio systems, home audio systems, and karaoke applications.
Feature Summary
- Integrated auto level control (ALC) function to avoid distortion due to clipping
- Adjustable voltage gain and ALC limit level using external resistors
- Switchable additional gain amplifier providing 0dB or +20dB options
- Built-in buffer amplifier and low equivalent input noise characteristics
Applications
- Mini component audio systems
- Home audio systems
- Karaoke equipment
Procurement Notes
Verify the specific package type and ordering suffix against official Nisshinbo Micro Devices documentation before procurement. Confirm that the SSOP14 package outline matches your PCB footprint requirements. Ensure that the operating voltage range aligns with your system's power supply specifications. Cross-reference the datasheet version number to ensure compatibility with your design parameters.
Selection Notes
Select this component when designing monaural microphone preamplifiers requiring automatic level control to manage signal peaks. Consider its adjustable gain range and limit levels for flexible circuit configurations. Evaluate the need for the built-in buffer amplifier and switchable additional gain features. Verify thermal performance within the specified operating temperature range for your application environment.
Part Context
The NJM2783 belongs to Nisshinbo Micro Devices' lineup of audio integrated circuits. It is part of the NJM27xx series, which focuses on microphone amplification solutions. The V-TE1 suffix indicates the SSOP14 package variant. This component leverages bipolar technology to deliver reliable performance in consumer audio applications.
Replacement Considerations
Consult official Nisshinbo Micro Devices documentation for confirmed substitute part numbers. Do not assume cross-compatibility with other manufacturers' microphone amplifiers without verifying pinouts, electrical characteristics, and functional equivalents.
FAQ
How is the ALC limit level adjusted?
The ALC limit level is adjustable by connecting external resistors to the SENSE pin.
What is the function of the GAIN SW pin?
The GAIN SW pin allows switching the additional gain amplifier between 0dB and +20dB modes.
Can the voltage gain be customized?
Yes, the voltage gain is adjustable by external resistors connected to the GAIN1 and GAIN2 pins.
