LM3886T Description
The LM3886T is a high-performance audio power amplifier capable of delivering 68W of continuous average power to a 4Ω load and 38W into 8Ω with 0.1% THD+N from 20Hz- 20kHz.
The performance of the LM3886T, utilizing its Self Peak Instantaneous Temperature (°Ke) (SPiKe) protection circuitry, puts it in a class above discrete and hybrid amplifiers by providing an inherently, dynamically protected Safe Operating Area (SOA). SPiKe protection means that these parts are completely safeguarded at the output against overvoltage, undervoltage, overloads, including shorts to the supplies, thermal runaway, and instantaneous temperature peaks.
The LM3886T maintains an excellent signal-to-noise ratio of greater than 92dB with a typical low noise floor of 2.0μV. It exhibits extremely low THD+N values of 0.03% at the rated output into the rated load over the audio spectrum, and provides excellent
linearity with an IMD (SMPTE) typical rating of 0.004%.
LM3886T Features
- 68W Cont. Avg. Output Power into 4Ω at Vcc = ±28V
- 38W Cont. Avg. Output Power into 8Ωat Vcc = ±28V
- 50W Cont. Avg. Output Power into 8Ω at Vcc =±35V
- 135W Instantaneous Peak Output Power Capability
- Signal-to-Noise Ratio ≥ 92dB
- An Input Mute Function
- Output Protection from a Short to Ground or to the Supplies via Intermal Current Limiting Circuitry
- Output Over-Voltage Protection against Transients from Inductive Loads
- Supply Under-Voltage Protection, not Allowing Internal Biasing to Occur when |Veel + |Vccl ≤ 12V, thus Eliminating Turn-On and Turn-Off Transients
- 11-Lead TO-220 Package
- Wide Supply Range 20V - 94V
