TI Enhances DTV Audio Performance with New Generation of Efficient Stereo Class-D Audio Power Amplifiers
Texas Instruments Incorporated has introduced two new stereo Class-D audio power amplifiers for digital televisions (DTV). The devices feature highly efficient Class-D operation and industry-leading audio performance, including pop/click-minimizing circuitry, low total harmonic distortion and excellent signal-to-noise ratio.
Device Designed to Speed Customers' Time-to-Market
The amplifiers' easy-to-use layout and low electromagnetic interference (EMI) speed the design cycle for manufacturers of medium- and large-screen DTVs including DLP® HDTV, liquid crystal display (LCD) and plasma.(See www.ti.com/sc06007.)
The TPA3100D2 drives up to 20 watts (W) per channel of continuous stereo output power with no external heat sink and is typically used in 27-inch and larger DTVs with the audio fidelity and form factors consumers demand. The TPA3101D2 is a pin-for-pin version with 10 W per channel output power that targets DTVs smaller than 27 inches. Both devices can drive a nominal load down to 4 ohms.
