A common misconception, the LM386 is NOT an op-amp. It's a power amp. Page edited accordingly.

The design is essentially that of an op-amp, but with higher powers involved. Differences are an internal feedback, and it drives much lower output impedances. The device is designed to be linear in voltage, and that makes it an op-amp, depending on feedback reactance. With resistive feedback, the transfer function is Vout = Hr + A Vin. Hr is half the rail voltage, and A is a constant. Vin is relative to signal ground. With reactive feedback, A is sensitive to the slew of Vin.220.244.73.11 (talk) 00:03, 24 September 2013 (UTC)[reply]

Thanks for the correction! —Ben Kovitz (talk) 21:53, 4 November 2013 (UTC)[reply]

Date of Release[edit]

The LM386 was not released in 1983. I have a 1977 National databook that has the LM386 in it. — Preceding unsigned comment added by 108.44.80.232 (talk) 02:06, 5 June 2018 (UTC)[reply]

Done - I agree, because the 1980 National databook had it too. • Sbmeirow • Talk • 02:24, 5 June 2018 (UTC)[reply]
