HANDLING
Inputs and outputs are protected against electrostatic discharges in normal handling. However, to be totally safe, it is
desirable to take normal precautions appropriate to handling integrated circuits.
CHARACTERISTICS
TDA8775 operating at 50 MHz; SLT = 1 and RL = 37.5 Ω.
VDDA = VDDD = 4.5 to 5.5 V; VSSA and VSSD shorted together; VDDA − VDDD = −0.5 to +0.5 V; Tamb = 0 to +70 °C; typical
values measured at VDDA = VDDD = 5 V and Tamb = 25 °C; unless otherwise specified.
