FAN7040 3W Mono BTL Amplifier with DC Volume Control • 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 • TVs and Monitors • Portable Computers • Desktop computers • Low Voltage Audio Systems 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 Internal Block Diagram FAN7040 Power Amp 14 OUT+ 17 OUT- DC Gain Control Missing current Bandgap protection Reference Over-Temperature Protection Power Amp 1-3, 8-13, 16, 18 and 20 SGND PGND 2004 Fairchild Semiconductor Corporation FAN7040 Pin Assignments FAN7040 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.
