TDA8768A
12-bit, 70 Msps Analog-to-Digital Converter (ADC)
Table 6: Characteristics…continued
VCCA = V2 to V44, V3 to V4 and V41 to V40 = 4.75 to 5.25 V; VCCD = V37 to V38 and V15 to V17 = 4.75 to 5.25 V;
VCCO = V33 to V34 = 3.0 to 3.6 V; AGND and DGND shorted together; Tamb = −40 to 85 °C; VI(p-p) − VI(p-p) = 1.9 V;
Vref = VCCA3−1.75 V; VI(CM) = VCCA3−1.6V; typical values measured at VCCA = VCCD = 5 V and VCCO = 3.3 V, Tamb = 25 °C
and CL = 10 pF; unless otherwise specified.
