www.fairchildsemi.com FAN7040 3W Mono BTL Amplifier with DC Volume Control Features • • • • • • • • • • DC Volume Control : +37dB ~ -52dB Few External Components Mute Mode Thermal Protection Short-Circuit Proof No Switch-On or Switch-Off Clicks Good Overall Stability Low Power Consumption Low HF Radiation ESD Protected On All Pins 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 portable recorders and radios. The device is contained in a 20-lead small outline package. A Missing Current Limiter(MCL) is built in. the MCL circuit 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 applications. 20SOP Applications • • • • TVs and Monitors Portable Computers Desktop computers Low Voltage Audio Systems 1 Internal Block Diagram VCC 4 FAN7040 IN 5 Power Amp 14 OUT+ VGA 17 OUT- VC 7 Missing current protection DC Gain Bandgap Control Reference Over-Temperature Protection 1-3, 8-13, 16, 18 and 20 6 Power Amp 15 NC SGND PGND Rev. 1.1.0 ©2004 Fairchild Semiconductor Corporation FAN7040 Pin Assignments 1 20 FAN7040 10 11 Pin Description Pin No 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 Symbol N.C.
