Digital Audio Amp Provides Six Channels

Emerging as the first single-package, six-channel digital-audio amplifier power stage, the TAS5186 supports five 30W channels and one 60W channel, providing more than 200W total. The 44-pin HTSSOP device employs a unique system pre-charge feature that eliminates pops and clicks on power up and a two-stage, over-current detector, which eradicates unnecessary shut downs while protecting against short circuit conditions. Its teammate, the TAS5086 PWM processor, operates at 3.3V and specifies a dynamic range in excess of 100 dB. In a 38-pin TSSOP, the processor also provides bass management and signal routing capabilities that allows the interfacing of any input channel to any output channel. Prices for the TAS5186 and TAS5086 are $5.12 and $1.59 each/1,000, respectively. TEXAS INSTRUMENTS INC., Dallas, TX. (800) 477-8924.
