Differential Line Receivers. Pulse Amplitude Compensation. Variable Attenuators. Voltage-Tunable Active Filters . 3 Description. The VCA821 device is a DC-coupled, wideband, linear in dB, continuously variable, voltage-controlled gain amplifier. It provides a differential Thermal FoldBack (TFB) with disable functionality. Fixed gain of 30 dB in SE and 36 dB in BTL applications. Fully short-circuit proof across load. BD modulation in BTL configuration. Clock protection. TDA8953. 2 210 W class- D power amplifier. Rev. 01 24 December 2009. Product data sheet conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. ( 2 ) The TPA3106D1 incorporates an exposed thermal pad on the underside of the chip. This acts as a heatsink, and it must be connected to a thermally dissipating plane for proper power dissipation. 4 x 50 W MOSFET quad bridge power amplifier. Features. High output power capability: 4 x 50 W/4 max. 4 x 30 W/4 @ 14.4 V, 1 kHz, 10 %. 4 x 80 W/ 2 max. 4 x 55 W/ 2 @ 14.4V, 1 kHz, 10 %. MOSFET output power stage. Excellent 2 driving capability. Hi-Fi class distortion. Low output noise.
