The LM1896 is a high performance 6V stereo power amplifier designed to deliver 1 watt per channel into 4X or 2 watts bridged monaural into 8X. Utilizing a unique patented compensation scheme, the LM1896 is ideal for sensitive AM radio applications. This new circuit technique exhibits lower wideband noise, lower distortion, and less AM radiation than conventional designs. The amplifier’s wide supply range (3V–9V) is ideal for battery operation. For higher supplies (VS > 9V), the LM2896 is available in an 11-lead single-in-line package. The LM2896 package has been redesigned, resulting in slightly degraded thermal characteristics shown in Figure 2.
The LM1896 and LM2896 are high‑performance stereo audio power amplifiers designed for low‑noise, low‑distortion operation in AM radio and portable stereo applications. They operate from a wide supply range (3 V‑15 V) and offer both dual‑channel and bridge configurations for flexible power output.
The document includes absolute maximum ratings, electrical characteristics, typical performance curves, application hints for AM radios, printed‑circuit‑board layout guidelines, and detailed mechanical dimensions for the dual‑in‑line and single‑in‑line packages.
| Supply Voltage Range | 3 V‑15 V |
|---|---|
| Output Power (Dual Mode) | 0.9 W per channel at 6 V, 4 Ω load |
| Output Power (Bridge Mode) | 1.8 W at 6 V, 8 Ω load |
| Power Supply Rejection Ratio (PSRR) | 54 dB |
| Input Impedance | 50 Ω |
The LM1896 operates from 3 V to 10 V, while the LM2896 version supports up to 15 V.
In dual‑channel mode it can deliver about 0.9 W per channel with a 6 V supply and a 4 Ω load.
