NJM2781V-TE1

Overview

The NJM2781V-TE1 is a monaural microphone amplifier IC manufactured by Nisshinbo Micro Devices Inc. It operates within a voltage range of +2.7V to +4.5V and features an adjustable voltage gain controlled by an external resistor. The device includes a standby function that reduces operating current to a maximum of 1µA. It utilizes bipolar technology and is housed in an SSOP8 package.

Feature Summary

• Integrated standby mode for significant power reduction
• Adjustable voltage gain via external resistor
• Low voltage operation suitable for portable devices

Applications

• Portable electronic components
• Handheld audio devices

Procurement Notes

Verify the specific ordering suffix 'V' corresponds to the SSOP8 package variant, as other suffixes like 'RB1' indicate different packages such as TVSP8. Confirm RoHS compliance status through official documentation before procurement.

Selection Notes

Select this component for applications requiring low-power monaural amplification with adjustable gain. Ensure the design accommodates the SSOP8 package dimensions and the required external resistor network for gain setting.

Part Context

This part belongs to the NJM2781 series of microphone preamplifiers. It is designed for battery-operated equipment where low power consumption and small footprint are critical requirements.

Replacement Considerations

The NJM2781RB1-TE1 serves as a functional substitute but utilizes a TVSP8 package instead of SSOP8. Verify pinout compatibility and physical space constraints when considering this alternative.
