TDA8703
CHARACTERISTICS
V_CCA = V₇ − V₃ = 4.5 V to 5.5 V; V_CCD = V₁₈ − V₂₀ = 4.5 V to 5.5 V; V_CCO = V₁₉ − V₂₀ = 4.5 V to 5.5 V; AGND and
DGND shorted together; V_CCA − V_CCD = −0.5 V to +0.5 V; V_CCO − V_CCD = −0.5 V to +0.5 V;
V_CCA − V_CCD = −0.5 V to +0.5 V; T_amb = 0 °C to +70 °C; unless otherwise specified (typical values measured at
V_CCA = V_CCD = V_CCO = 5 V and T_amb = 25 °C).
