Overview
The NJM2781RB2-TE1 is a monaural microphone amplifier IC manufactured by Nisshinbo Micro Devices Inc. It features a standby function and adjustable voltage gain via an external resistor. The device operates within a supply voltage range of +2.7V to +4.5V, with a typical operating current of 1.8mA in active mode and a maximum of 1µA in standby. It utilizes bipolar technology and is available in MSOP8(TVSP8) packages.
Feature Summary
- Integrated standby control for power management
- Adjustable voltage gain using external components
- Low voltage operation suitable for portable devices
Applications
- Portable audio equipment
- Handheld electronic devices
- Microphone pre-amplification circuits
Procurement Notes
Verify the specific package variant (MSOP8 vs SSOP8) against the datasheet, as the RB2 suffix indicates a specific form factor distinct from other NJM2781 versions. Confirm availability through authorized distributors or direct manufacturer channels, as stock levels fluctuate. Ensure ordering quantities align with standard packaging requirements.
Selection Notes
Select this component when a low-power, single-channel microphone amplifier with standby capability is required. Consider the MSOP8 package size for space-constrained designs. Verify that the required voltage gain can be achieved with the intended external resistor values and that the supply voltage remains within the specified 2.7V to 4.5V range.
Part Context
This part belongs to the NJM2781 series of monaural microphone amplifiers. The series includes variants like NJM2781V (SSOP8) and NJM2781RB1 (MSOP8). The NJM2781RB2-TE1 specifically denotes the MSOP8(TVSP8) package version, designed for compact applications requiring low power consumption and high performance.
Replacement Considerations
Direct replacements include NJM2781RB1-TE2 for the same MSOP8 package type. For SSOP8 packages, the NJM2781V-TE1 is the equivalent alternative. Ensure pin compatibility and electrical specifications match before substitution.
