NJM2113L

Overview

The NJM2113L is a Class AB mono audio amplifier IC manufactured by Nisshinbo Micro Devices. It operates within a supply voltage range of 2V to 16V and delivers a maximum output power of 400mW into a 100-ohm load. The device features a typical operating current of 2.7mA and supports a CD input function for power-down with mute capabilities. It is designed for low-voltage applications and operates across a temperature range of -20°C to +75°C.

Feature Summary

• Class AB mono audio amplification architecture
• Wide operating voltage range from 2V to 16V
• CD input functionality for integrated power-down and mute control

Applications

• Embedded electronics systems
• Industrial equipment audio interfaces
• Low-voltage consumer audio devices

Procurement Notes

Verify the specific suffix 'L' indicates the correct package variant, as other suffixes like 'D' or 'M' denote different physical packages such as DIP or SOIC. Confirm RoHS compliance status through official documentation. Ensure the design accommodates the specified thermal characteristics and operating temperature limits for the intended environment.

Selection Notes

Select this component when a single-channel Class AB amplifier is required for low-voltage operation up to 16V. Consider the 400mW output capability relative to the target load impedance. Evaluate the need for the specific CD input control feature versus standard mute pins available in other variants within the NJM2113 series.

Part Context

The NJM2113L belongs to the NJM2113 series of audio amplifiers produced by Nisshinbo Micro Devices. This series includes variants with different packaging options, such as the NJM2113D in an 8-DIP package and the NJM2113M in an 8-SOIC package. All variants share similar electrical performance characteristics regarding voltage range and output power.

Replacement Considerations

Direct substitutes include NJM2113D and NJM2113M, provided the package difference (DIP vs. SOIC) is acceptable for the PCB layout.
