TPA2012D2RTJT 2.1W stereo Class D audio power amplifier

illustrate   The TPA2012D2 is a stereo, filterless Class D audioamplifier (Class D amplifier) in a WCSP package, QFN package, or utility package. The operation of this TPA2012D2 requires only two external components. The TPA2012D2 features independent shutdown control for each channel. Gain of 6, 12, 18, or 24 dB can be selected using the gain selection pins of G0 and G1. High PSRR and differential structure provide more immunity, noise and RF rectification. In addition to these features, fast start-up times and a small package make TPA2012D2 Class-D amplifiers ideal for mobile phones and PDAs. The TPA2012D2 is a 1.4 W power drive capability / 5 V or 720 megawatts channel/channel at 3.6 volts to 8Ω. The TPA2012D2 is also a drive 4a3A9能力.   characteristic   Output Power Package: QFN package: 2.1 watts/channel at 5 V divided into 4 Ω 8Ω at 1.4 watts/channel 5 V 720 mW/channel at 3.6 volts to 8 Ω Using WCSP: 1.2 watts/total score 4a3A9; At 5 V (1) 1.3 watts/total score 8a3A9; At 5V The total score of 720 mW/A9 is 8; at 3.6 volts There are only two required external elements Supply voltage range: 2.5 V to 5.5 V Independent shutdown control for each channel Optional gains are 6, 12, 18 and 24 dB Pull down the resistor inside the shutdown pin High PSRR: 77 Hz 217 dB Fast start-up time (3.5 ms) Low supply current Low shutdown current Short circuit and thermal protection Space-saving package
