5.8W AUDIO POWER AMPLIFIER. 19W BTL AUDIO POWER AMPLIFIER.
The TA7270P/TA7271P are dual AUDIO power amplifier for consumer applications. It is designed for high power, low distorion and low noise. It also contains various kind of protectors. Its suitable for car-AUDIOj power amplifier with high performance.
DESCRIPTION The PT2314E is an AUDIO processor designed for versatile application, includes 4 stereo input selector with adjustable gain, master volume control with low frequency loudness compensation, speaker output attenuator and tone control. It is a good solution for the home AUDIO signal processing. Due to the high reliability requirement from the AUDIO business, the PT2314E improves both AUDIO performances and input surge current capability, these causes the PT2314E is the best solution for the cost-effective AUDIO systems.
FEATURES • 4 stereo inputs with gain selection, range from 0dB to +11.25dB in 3.75dB/step • Master volume from 0 dB to -78.75dB in 1.25dB/step • Speaker attenuator for balance, range from 0dB to -38.75dB in 1.25dB/step • Each channel output can be muted individually. • Low frequency loudness compensation • Bass and Treble control, range from -14dB to +14dB in 2dB/step • Wide operation range (VDD=4V to 10V) • Low harmonic distortion, low noise • Improved and replace PT2314 and PT2314A
APPLICATIONS • Flat Panel TV • Home AUDIO System • Powered Speaker System
GENERAL DESCRIPTION The TDA9614H is an AUDIO processing IC for VHS hi-fi and linear AUDIO, digitally controlled via the I2C-bus. The FM (de)modulator and peak noise reduction functions are highly integrated, resulting in few external components and no external adjustments.
FEATURES • All functions controlled by I2C-bus • No adjustments needed by use of auto-calibration circuit • Integrated Bandpass Filters (BPFs) • Low-noise Phase-Locked Loop (PLL) FM (de)modulator • Low-distortion sample-and-hold switching noise suppressor • Integrated HF Low-Pass Filter (LPF) and summator • Integrated AUDIO LPF • 5 stereo inputs (left and right channel): – TUNL and TUNR – CINL and CINR – EXT1L and EXT1R – EXT2L and EXT2R – EXT3L and EXT3R • Additional mono input: Second AUDIO Program (SAP) • Independent Input/Output (I/O) selections and 2nd line output • Linear AUDIO • DC output for VU meter drive • Direct headphone drive • RF converter output with overload Automatic Gain Control (AGC) • Integrated standby mode for low current consumption • E-E performance (record + playback): – Total Harmonic Distortion (THD): 0.05% (−8 dBV, 1 kHz) – linearity error: 0.1 dB (−88 dBV, 1 kHz) – noise: −93 dBV (20 Hz to 20 kHz).
