5 / 10 page July 1994 5 Philips Semiconductors Objective specification Single BTL power driver TDA7072A/AT CHARACTERISTICS VP = 5 V; f = 1 kHz; Tamb = 25 °C; unless otherwise specified (see Fig.3>). TDA7072A: RL = 8 Ω; TDA7072AT: RL = 16 Ω. Notes to the characteristics 1. With a load connected to the outputs the quiescent current will increase, the maximum value of this increase being equal to the DC output offset voltage divided by RL. 2. The output voltage swing is typically limited to 2 x (VP −2.1 V) (see Fig.4). 3. The noise output voltage (RMS value), unweighted (20 Hz to 20 kHz) is measured with RS = 500 Ω. 4. The ripple rejection is measured with RS = 0 Ω and f = 100 Hz to 10 kHz. The ripple voltage of 200 mV (RMS value) is applied to the positive supply rail. 5. The DC common mode voltage range is limited to (VP −2.2 V). 6. The common mode rejection ratio is measured at Vref = 1.4 V, VI(CM) = 200 mV and f = 1 kHz. SYMBOL PARAMETER CONDITIONS MIN. TYP. MAX.
