TDA8712; TDF8712

QUICK REFERENCE DATA

Notes

1. D0 to D7 are connected to VCCD and CLK is connected to DGND.

2. The analog output voltages (VOUT and VOUT) are negative with respect to VCCA (see Table 1). The output resistance

between VCCA and each of these outputs is typically 75 Ω.

3. The

−3 dB analog output bandwidth is determined by real time analysis of the output transient at a maximum input

code transition (code 0 to 255).
