TDA8764
CHARACTERISTICS
The characteristics given refer to the SSOP28 package. V_CCA = V₃ to V₄ = 4.75 to 5.25 V;
V_CCD = V₁₁ to V₁₂ and V₂₈ to V₂₇ = 4.75 to 5.25 V; V_CCO = V₁₃ to V₁₄ = 2.7 to 3.6 V; AGND and DGND shorted
together; T_amb = 0 to 70 °C; typical values measured at V_CCA = V_CCD = 5 V and V_CCO = 3.3 V; C_L = 10 pF and
T_amb = 25 °C; unless otherwise specified.
