NTE1667
Integrated Circuit 2 Channel Amp, 2.3W/Ch (4.7W BTL)

Features:
- Has Two Channels that can be used for Either Stereo or Bridge Amplifier
- High Outputs:
2 Channel (2.3W/Ch @ VCC = 9V, RL = 4Ω)
Bridge Amp (4.7W @ VCC = 9V, RL = 8Ω)
- Voltage Gain is Variable by Externally Connected Feedback Resistors: 2 Channel (RNF = 27Ω, VG = 50dB)
Bridge Amp (RNF = 51Ω, VG = 51dB)
- Switching Distortions in Higher Frequencies have been Held Low
- The Built-In Muting Circuit Keeps Noise caused by Turning Power ON and OFF at Low Levels
- The Built-In Ripple Filter Provides Good Ripple Rejection Factors
- Excels in Channel Separation
