Overview
The NJM2135M 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, it draws approximately 2.7mA, while power down mode reduces current to 0.1µA typ. Output power exceeds 250mW at 6V with a 32Ω load. The closed-loop gain is adjustable via two external resistors.
Feature Summary
- Differential output architecture removes requirement for external coupling capacitors
- Low operating current in both active and power down modes
- Adjustable closed-loop gain controlled by external resistors
- Bipolar technology construction
Applications
- Speaker driver circuits
- Portable battery powered equipment
- Cellular phones
Procurement Notes
Verify the specific package variant against the datasheet outline options (DIP8, DMP8, SIP8, SSOP8, VSP8) as the 'M' suffix indicates a specific package type. Confirm pinout compatibility with the provided configuration table before integration. Ensure thermal management meets the specified power dissipation limits based on ambient temperature conditions.
Selection Notes
Select this component when designing low voltage audio systems requiring high efficiency and minimal external passive components. The differential output simplifies board layout by removing large coupling capacitors. Consider the power down feature for applications requiring significant standby current reduction, such as mobile devices.
Part Context
The NJM2135 belongs to Nisshinbo Micro Devices' lineup of low voltage audio power amplifiers. It is part of a family offering various package outlines including DIP, SIP, SSOP, and VSP formats. The device is engineered for portable electronics where power consumption and space constraints are critical design factors.
Replacement Considerations
Consult official documentation for direct substitutes. Verify pinout and electrical characteristics match if considering alternative packages like NJM2135V or NJM2135R.
