NTE1851 24W BTL Audio Amplifier IC
Formerly: ECG1851
Integrated Circuit
Audio Amplifier, 24W BTL
Description:
The NTE1851 is a monolithic integrated class−B amplifier in a 13−Lead Staggered SIP type package
primarily developed for car radio applications, and also to drive low−impedance loads (down to 1.6Ω).
At a supply voltage VCC = 14.4V, an output power of 21W can be delivered into a 4Ω BTL (Bridge−Tied
Load), or, when used as a stereo amplifier, it delivers 2 x 11W into 2Ω or 2 x 6.5W into 4Ω.
Features:
- Flexibility In Use − Mono BTL as well as Stereo
- High Output Power
- Low Offset Voltage at the Output
(Important for BTL)
- Large Usable Gain Variation
- Very Good Ripple Rejection
- Internal Limited Bandwidth for High Frequencies
- Low Standby Current Possiblity (1μA Typ), to
Simplify Required Switches: TTL Drive Possible
- Low Number of Small−Sized External Components
- High Reliability
- Load Dump Protection
- AC and DC Short−Circuit Safe to Ground up to
VCC = 18V
- Thermal Protection
- Speaker Protection in Bridge Configuration
- SOAR Protection
- Outputs Short−Circuit Safe to Ground in BTL
- Reverse−Polarity Safe
Applications:
- Car Radio Applications
- Drive Low Impedance Loads
- Stereo Amplifier
