Product speciﬁcation

Dual BTL power driver

TDA7073A; TDA7073AT

CHARACTERISTICS

VP = 5 V; f = 1 kHz; Tamb =25 °C; unless otherwise speciﬁed (see Fig.3). TDA7073A: RL =8 Ω; TDA7073AT: RL =16 Ω.

Notes

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

× (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 with a maximum of 10 V).

6. The common mode rejection ratio is measured at Vref = 1.4 V, VI(CM) = 200 mV and f = 1 kHz.
