LM4922 Overview
Key Specifications
Mount Type: Surface Mount
Pins: 14
Operating Voltage: 3 V
Max Voltage (typical range): 4.2 V
Description
The LM4922 is a ground referenced, fixed-gain audio power amplifier capable of delivering 80mW of continuous average power into a 16Ω single-ended load with less than 1% THD+N from a 3V power supply. The LM4922 features a new circuit technology that utilizes a charge pump to generate a negative reference voltage.
Key Features
- a new circuit technology that utilizes a charge pump to generate a negative reference voltage
- This allows the outputs to be biased about ground, thereby nating output-coupling capacitors typically used with normal single-ended loads
- The LM4922 features an Automatic Standby Mode circuitry (patent pending)
- In the absence of an input signal, after approximately 12 seconds, the LM4922 goes into low current standby mode
- The LM4922 recovers into full power operating mode immediately after a signal is applied to either the left or right input pins
