Laptop Chip GMT G1431 2W Stereo Audio Amplifier
Description:
G1431 is a stereo audio power amplifier in 20pin TSSOP thermal pad package. It can drive 2.0W continuous RMS power into 4Ω load per channel in Bridge-Tied Load (BTL) mode at 5V supply voltage. Its THD is smaller than 1% under the above operation condition. To simplify the audio system design in the notebook application and to enlarge the driving power,G1431 supports the Bridge-Tied Load (BTL) mode for driving the speakers. For the low current consumption applications, the SHDN mode is supported to disable G1431 when it is idle. The current consumption can be
reduced to 150μA (typically).
Amplifier gain is internally configured and controlled by two terminals (GAIN0, GAIN1). BTL gain settings of 6dB, 10dB, 15.6dB, 21.6dB are provided.
Features:
- Internal Gain Control, Which Eliminates External Gain-Setting Resistors
- Depop Circuitry Integrated
- Output Power at 1% THD+N, VDD=5V
