Audio power amplifier integrates fault detection functions

Santa Clara, Calif.—National Semiconductor Corp. is offering a monolithic amplifier for automotive warning and alert tone amplification. The LM48100Q amplifies warning tones in automobile driver warning systems such as signal change, back up warning and collision avoidance.

The LM48100Q Boomer audio power amplifier is AEC-Q100 Grade 2 qualified for operation between -40°C and 105°C. The mono 1.3W amplifier offers key features to ensure that the speaker and amplifier always operate. They include an open drain FAULT output that indicates when a fault has occurred; and comprehensive output short circuit and thermal overload protection that prevents damage during a fault condition.

The LM48100Q offers dual audio inputs that can be mixed and multiplexed to the device output, with each path having its own independent 32 step volume control. It offers low quiescent current of 6 mA at 5V.

Pricing: $1.50 each in 1,000-unit quantities.
