Product specification
TDA8772
CHARACTERISTICS
TDA8772H/3 operating at 35 MHz and TDA8772H/8 operating at 85 MHz unless otherwise specified.
V_DDA = V_DDD = 4.5 V to 5.5 V; V_SSA and V_SSD shorted together; V_DDA − V_DDD = −0.5 V to +0.5 V; T_amb = 0 to +70 °C;
typical values measured at V_DDA = V_DDD = 5 V and T_amb = 25 °C; unless otherwise specified.
