NTE1637
Integrated Circuit
Dual AF Power Ampilifier, 4.3W
Features:
D Built−in 2 Channels Enabling use in Stereo and Bridge Amplifier Applications.
D Low Switching Distortion at High Frequencies
D Minimum Number of External Parts Required: 9 Pcs. Min. (Stereo/Bridge)
D Small Shock Noise at the Time of Power Supply ON/OFF due to Built−In Muting Circuit
D Good Ripple Rejection due to Built−In Ripple Filter
D Voltage Gain Fixed at 45dB (Bridge: 51dB). VariableVoltage Gain Available with External Re-
sistor Added.
D Easy to Mount on Board and also easy to Design Radiator fin due to use of 14−Pin SIP
