Product specification
8-bit, 40 Msps 2.7 to 5.5 V universal
analog-to-digital converter
TDA8790
Notes
1.
In addition to a good layout of the digital and analog ground, it is recommended that the rise and fall times of the clock
must not be less than 1 ns.
Analog input voltages producing code 0 up to and including 256:
a) V
osB
(voltage offset BOTTOM) is the difference between the analog input which produces data equal to 00 and
the reference voltage BOTTOM (V
RB
) at T

°
C.
b) V
osT
(voltage offset TOP) is the difference between V
RT
(reference voltage TOP) and the analog input which
produces data outputs equal to 256 at T
