1 / 22 page  © Semiconductor Components Industries, LLC, 2006 January, 2006 − Rev. 8 1 Publication Order Number: NCP2809/D NCP2809 Series NOCAPt 135 mW Stereo Headphone Power Amplifier The NCP2809 is a cost−effective stereo audio power amplifier capable of delivering 135 mW of continuous average power per channel into 16 W loads. The NCP2809 audio power amplifier is specifically designed to provide high quality output power from low supply voltage, requiring very few external components. Since NCP2809 does not require bootstrap capacitors or snubber networks, it is optimally suited for low−power portable systems. NCP2809A has an internal gain of 0 dB while specific external gain can externally be set with NCP2809B. If the application allows it, the virtual ground provided by the device can be connected to the middle point of the headset (Figure 1). In such case, the two external heavy coupling capacitors typically used can be removed. Otherwise, you can also use both outputs in single ended mode with external coupling capacitors (Figure 43). Due to its excellent Power Supply Rejection Ratio (PSRR), it can be directly connected to the battery, saving the use of an LDO. Features • 135 mW to a 16 W Load from a 5.0 V Power Supply • Excellent PSRR (85 dB Typical): Direct Connection to the Battery • “Pop and Click” Noise Protection Circuit • Ultra Low Current Shutdown Mode • 2.2 V–5.5 V Operation • Outstanding Total Harmonics Distortion + Noise (THD+N): Less than 0.01% • External Turn−on and Turn−off Configuration Capability • Thermal Overload Protection Circuitry • Pb−Free Packages are Available Typical Applications • Cellular Phone • Portable Stereo • MP3 Player • Personal and Notebook Computers Micro10 DM SUFFIX CASE 846B 1 10 PIN CONNECTIONS IN_R OUT_R SD BYP REF_I VM VP 110 2 3 4 9 8 7 MARKING DIAGRAM IN_L 5 OUT_L 6 MAx AYW G G OUT_I See detailed ordering and shipping information in the package dimensions section on page 20 of this data sheet.
