NJM2135M-TE1

Overview

The NJM2135M-TE1 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 delivers an output power exceeding 250mW at 6V with a 32Ω load. It includes a power-down mode with typical operating current of 0.1µA. The closed-loop gain is adjustable via two external resistors, offering a voice band gain range of 0 to 43dB.

Feature Summary

• Differential output architecture removes requirement for external coupling capacitors
• Low operating current in normal mode reduces power consumption for battery equipment
• Power-down standby mode significantly minimizes supply current draw
• Closed-loop gain adjustment provided through two external resistors

Applications

• Speaker driver circuits
• Portable battery powered equipment
• Cellular phones

Procurement Notes

Verify the specific package suffix matches the required form factor, as the NJM2135 series utilizes multiple outlines including DIP8, DMP8, SIP8, SSOP8, and VSP8. Confirm the TE1 designation corresponds to the correct reel packaging configuration. Ensure the component meets RoHS requirements if applicable to the target assembly process. Cross-reference the datasheet version to confirm electrical characteristics align with design specifications.

Selection Notes

Select this component when designing low voltage audio systems requiring differential outputs without coupling capacitors. Consider the 2V to 16V operating range for compatibility with various single-supply configurations. Evaluate the 250mW output capability against the specific load impedance requirements. Review the power dissipation characteristics relative to the expected ambient temperature conditions during operation.
