NJM2135M-TE2#

Overview

The NJM2135M-TE2 is a low voltage audio power amplifier utilizing bipolar technology, designed for speaker drivers. It features a differential output that eliminates the need for external coupling capacitors. The device operates within a supply voltage range of +2V to +16V and supports load impedances from 8Ω to 200Ω. In normal operation at 6V, it delivers over 250mW of output power with a typical operating current of 2.7mA. The part is housed in an SSOP-8 package.

Feature Summary

• Differential output architecture removes the requirement for external coupling capacitors
• Low standby current consumption in power down mode reduces battery drain
• Closed-loop gain is adjustable via two external resistors
• Operates on a single power supply ranging from +2V to +16V

Applications

• Speaker drivers
• Portable battery-powered equipment
• Cellular phones

Procurement Notes

Verify the specific ordering suffix TE2 against the manufacturer's official documentation to confirm reel packaging specifications. Ensure the component matches the SSOP-8 package outline and verify RoHS compliance status through the latest datasheet revision before procurement.

Selection Notes

Select this component for applications requiring a single-supply audio amplifier without output capacitors. Consider the 2.7mA typical operating current for battery life calculations. Verify that the required gain range of 0 to 43dB fits the system design and that the load impedance falls within the 8Ω to 200Ω specification.

Part Context

This component belongs to the NJM2135 series of low voltage audio power amplifiers manufactured by Nisshinbo Micro Devices.
