APA0715

APA0715 3W Mono Fully Differential Audio Power Amplifier Features General Description The APA0715 is a Mono, fully differential Class-AB audio amplifier which can operate with supply voltage from 2.4V to 5V and is available in a MSOP8, MSOP8P, or TDFN3x38 package. High PSRR and fully differential architecture increase immunity to noise and RF rectification. In addition to these features, a short startup time and small package size make the APA0715 an ideal choice for Mobil Phones and Portable Devices. The APA0715 also integrates the de-pop circuitry that reduces the pops and click noises during power on/off and shutdown mode operation. Both Thermal and over-current protections are integrated to avoid the IC being destroyed by over temperature and short-circuit. The APA0715 is capable of driving 3W at 5V into 3 Ω speaker. • • • • • • • • Operating Voltage: 2.4V~5.5V Fully Differential Class-AB Amplifier High PSRR and Excellent RF Rectification Immunity Low Crosstalk 3W Output Power into 3Ω Load at VDD=5V Thermal and Over-Current Protections Low Supply Current :1.5mA Typical Space Saving Package -MSOP-8 -MSOP-8P -TDFN3x3-8 Lead Free and Green Devices Available (RoHS Compliant) • Applications Pin Configuration SD 1 BYPASS 2 INP 3 MSOP-8 Top View 8 OUTN 7 GND 6 VDD 5 OUTP • • Mobil Phones Portable Devices Simplified Application Circuit INN 4 SD 1 BYPASS 2 INP 3 INN 4 MSOP-8P Top View 8 OUTN 7 GND 6 VDD 5 OUTP LINN Input LINP LOUTP APA0715 LOUTN Speaker SD 1 BYPASS 2 INP 3 INN 4 TDFN3x3-8 TOP View 8 OUTN 7 GND 6 VDD 5 OUTP =Thermal Pad (connected the Thermal Pad to GND plane for better heat dissipation) ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and advise customers to obtain the latest version of relevant information to verify before placing orders.
