TS2007 3 W filter-free Class D audio power amplifer with 6-12 dB fixed gain select Features Operating range from V = 2.4 V to 5.5 V CC Standby mode active low TS2007IQT - DFN8 Output power: 1.4 W at 5 V or 0.45 W at 3.0 V into 8 with 1% THD+N max. Output power: 2.3 W at 5 V or 0.75 W at 3.0 V into 4 with 1% THD+N max. Fixed gain select: 6 dB or 12 dB Low current consumption Efficiency: 88% typ. Signal-to-noise ratio: 94 dB typ. PSRR: 63 dB typ at 217 Hz with 6 dB gain TS2007IQT - DFN8 PWM base frequency: 280 kHz Low pop & click noise Thermal shutdown protection 88 11 DFN8 3 x 3 mm package 22 77 Applications 33 66 Cellular phones PDAs 55 44 Notebook PCs Description The TS2007 is a class D power audio amplifier. The TS2007 is available in DFN8 3 x 3 mm lead- Able to drive up to 1.4 W into an 8 load at 5 V, it free packages. achieves outstanding efficiency compared to typical class AB audio power amplifiers. This device allows switching between two different gains: 6 or 12dB via a logic signal on the GS pin. A pop & click reduction circuitry provides low on/off switching noise while allowing the device to start within 5 ms. A standby function (active low) allows lowering the current consumption down to 10 nA typ.
