Product specification
TDA8709A
CHARACTERISTICS
V_CCA = V₂₂ to V₂₃ = 4.5 to 5.5 V; V_CCD = V₆ to V₈ = 4.5 to 5.5 V; V_CCO = V₇ to V₈ = 4.2 to 5.5 V; AGND and DGND
shorted together; V_CCA to V_CCD = −0.5 to +0.5 V; V_CCO to V_CCD = −0.5 to +0.5 V; V_CCA to V_CCO = −0.5 to +0.5 V;
T_amb = 0 to +70 °C; typical readings taken at V_CCA = V_CCD = V_CCO = 5 V and T_amb = 25 °C; unless otherwise specified.
