FAN7023MUX

www.fairchildsemi.com FAN7023 Features 1W CMOS Mono Power Amplifier Description The FAN7023 is a bridge connected audio power amplifier capable of delivering 1W of continuous average power to an 8Ω load with less than 0.2%(THD) from a 5V power supply. The FAN7023 requires few external components and operates on low supply voltage from 2.2V to 5.5V. Since the FAN7023 does not require output coupling capacitors, bootstrap capacitors, or snubber networks, it is ideally suited for low power portable systems that require minimum volume and weight. The FAN7023 features an externally controlled gain, low power consumption shutdown mode (0.01uA,typ.). Additional FAN7023 features include thermal shutdown protection, unity gain stability, and external gain set. 8-MSOP 10-MLP 1 BOTTOM VIEW • Continuous Average Power is 1.0W (8Ω) • Low THD: Typical 0.2% @ 1kHz (5V) • Do Not Need Output Coupling Capacitor or Bootstrap Capacitor • Low Shutdown Current: Typical 0.01µA • Shutdown: High Active • Built in TSD Circuit Typical Applications • Cellular Phone • PDA • Portable Audio Systems 1 8-SOP 1 Internal Block Diagram 4 3 IN- VO1 5 IN+ 20kΩ 2 BP 100kΩ 6 VDD BIAS 100kΩ VDD/2 VO2 8 20kΩ 1 SD GND 7 Rev. 1.1.0 ©2003 Fairchild Semiconductor Corporation FAN7023 Pin Assignments VO2 8 GND 7 VDD 6 VO1 5 VO2 10 9 8 7 6 1 2 3 4 5 SD BP GND IN+ IN- FAN7021 FAN7023 NC VDD NC VO1 1 SD 2 BP 3 IN+ 4 IN- 10-MLP(BOTTOM VIEW) Pin Definitions Pin Number 1(1) 2(2) 3(4) 4(5) 5(6) 6(8) 7(3) 8(10) Pin Name SD BP IN+ INVO1 VDD GND VO2 Shutdown Bypass Input+ InputPower AMP Output1 Supply Voltage Ground Power AMP Output2 Pin Function Description ( ) : 10MLP Absolute Maximum Ratings (Ta = 25°C) Parameter Maximum Supply Voltage Power Dissipation Operating Temperature Storage Temperature Junction Temperature Thermal Resistance (Junction to Ambient) Symbol VDD PD TOPR TSTG TJ Rthja Value 6.0 Internally Limited -40 ~ +85 -65 ~ +150 150 190 166 50 °C/W Unit V W °C °C °C 8MSOP 10MLP, Single-Layer 10MLP, Multi-Layer Remark Recommended Operating Conditions (Ta = 25°C) Parameter Operating Supply Voltage Symbol VDD Min. 2.2 Typ.
