Product speciﬁcation

8-bit high-speed analog-to-digital converter

TDA8714

CHARACTERISTICS

VCCA =V7 to V6 = 4.75 to 5.25 V; VCCD =V18 to V17 = 4.75 to 5.25 V; VCCO =V19 and V21 to V20 = 4.75 to 5.25 V;

AGND and DGND shorted together; VCCA to VCCD = −0.25 to +0.25 V; VCCO to VCCD = −0.25 to +0.25 V;

VCCA to VCCO = −0.25 to +0.25 V; Vi(p-p) = 1.75 V; Tamb = 0 to +70 °C; typical values measured at

VCCA =VCCD =VCCO = 5 V and Tamb =25 °C; unless otherwise speciﬁed.
