ADC0804S030/040/050
Single 8 bits ADC, up to 30 MHz, 40 MHz or 50 MHz
[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 0.5 ns.

Analog input voltages producing code 0 up to and including code 255:
a) V
offset
BOTTOM is the difference between the analog input which produces data equal to 00 and the reference voltage on pin RB
(V
RB
) at T
amb
= 25
°
C.
b) V
offset
TOP is the difference between the reference voltage on pin RT (V
RT
) and the analog input which produces data outputs equal
to code 255 at T
amb
= 25
°
C
.
To ensure the optimum linearity performance of such a converter architecture the lower and upper extremities of the converter reference
resistor ladder are connected to pins RB and RT via offset resistors R
OB
and R
OT
as shown in
Figure 3

a) The current flowing into the resistor ladder is
and the full-scale input range at the converter, to cover code 0
to 255 is
b) Since R
L
, R
OB
and R
OT
have similar behavior with respect to process and temperature variation, the ratio
will be kept reasonably constant from device to device. Consequently, the variation of the output codes at a given input voltage
depends mainly on the difference V
RT
V
RB
and its variation with temperature and supply voltage. When several ADCs are
connected in parallel and fed with the same reference source, the matching between each of them is optimized.

[5]
The analog bandwidth is defined as the maximum input sine wave frequency which can be applied to the device. No glitches greater
than 0.5 LSB, neither any significant attenuation are observed in the reconstructed signal.
[6]
The analog input settling time is the minimum time required for the input signal to be stabilized after a sharp full-scale input (square
wave signal) in order to sample the signal and obtain correct output data.
