5 / 13 page 1995 Dec 15 5 Philips Semiconductors Product specification Dual common-mode rejection differential line receiver TDA8579 CHARACTERISTICS VCC = 8.5 V; Tamb =25 °C; f = 1 kHz; measured in test circuit of Fig.3; unless otherwise specified. Notes 1. The DC output voltage with respect to ground is approximately 0.5VCC. 2. The frequency response is externally fixed by the input coupling capacitors. 3. The noise output voltage is measured in a bandwidth of 20 Hz to 20 kHz (unweighted). 4. The common-mode rejection ratio is measured at the output with a voltage source 1 V (RMS) in accordance with the test circuit (see Fig.3) while VINL and VINR are short-circuited. Frequencies between 100 Hz and 100 kHz. 5. The ripple rejection is measured at the output, with Rs =2kΩ, f = 1 kHz and a ripple amplitude of 2 V (p-p). 6. The ripple rejection is measured at the output, with Rs = 0 to 2 kΩ, f = 100 Hz to 20 kHz and a maximum ripple amplitude of 2 V (p-p). SYMBOL PARAMETER CONDITIONS MIN. TYP. MAX.
