Description
The NJM2149 is an audio power amplifier designed for telephone applications. It eliminates the need for external coupling capacitors since it has differential outputs. The circuit's closed loop gain is regulated by two external resistors, and it has a CD pin that allows for power-down while muting the input signal.
Specifications and features

- Operating Current: 2.2mA typ., at V+ =3V
- Supply Current in Power Down Mode: 0.1µA typ
- Output Power Exceeds: 250mW V+ =6V, RL=32Ω
- Gain Range: GVD=0-43dB, Voise Band
- Load Impedance: RL=8-200Ω
- Technology: Bipolar
- Package Outline: DIP8, DMP8, SSOP8, VSP8, TVSP8
Application Scenarios
The NJM2149 audio power amplifier is a great fit for telephone systems. Its differential outputs eliminate the need for external coupling capacitors, which makes it very appealing for manufacturers. The gain range is easily adjustable using external resistors.
Comparison
Advantages- Eliminates the need for external coupling capacitors
- Gain range can be easily adjusted using external resistors
- Can be powered down with muting the input signal
Disadvantages- Load impedance is limited to RL=8-200Ω
- The output power is limited to 250mW V+ =6V, RL=32Ω, which may not be sufficient for some applications
