386N Audio Power Amp 1 WATT 8pin
Description:
- The LM386N is a power amplifier that can provide up to one watt of output power.
- It is renowned for its versatility and efficiency in a wide range of low-voltage audio applications, including portable speakers, intercoms, and radio systems.
- The amplifier's gain is set to 20 internally, but it can be raised to any value between 20 and 200 by connecting an external resistor and capacitor.
Specifications:
- Supply Voltage (Vs): 4V to 12V (LM386N-1, -3) or 5V to 18V (LM386N-4).
- Quiescent Current (Iq): 4mA.
- Output Power (Pout):
- 250mW at Vs = 6V, RL = 8Ω.
- 1W at Vs = 12V, RL = 8Ω.
- Voltage Gain: Internally set to 20 (26 dB), adjustable to any value between 20 and 200 (46 dB) with external resistor and capacitor.
- Input Resistance (Rin): 50kΩ.
- Bandwidth: 300 kHz (at gain = 20).
- Total Harmonic Distortion (THD): 0.2% (at 125mW output power, 1 kHz).
- PSRR (Power Supply Rejection Ratio): 50dB (at f = 1 kHz, gain = 20).
- Input Bias Current (Ib): 250nA.
- Input Offset Voltage (Vio): 5mV.
- Slew Rate: 0.5V/µs.
