Description
The FAN7040 is a mono Bridge-Tied Load(BTL) output
amplifier with DC volume control. It is designed for use in
TVs and monitors, but is also suitable for battery-fed porta-
ble recorders and radios. The device is contained in a 20-lead
small outline package.
A Missing Current Limiter(MCL) is built in. the MCL cir-
cuit is activated when the difference in current between the
output terminal of each amplifier exceeds 130mA. This level
of 130mA allows for Single-Ended(SE) headphone applica-
tions.
