NAME
FUNCTION
1
CS
Chip Select Input.
CS
must be low for the device to be selected or to recognize the
RD
input.
Read Input.
RD
must be low to access data.
RD
is also used to start conversions. See the
Microprocessor Interfacesection.

TIMING CHARACTERISTICS (Note 5)
(V
DD
= +5V, V
REF
= 1.23V, AGND = DGND = 0V.)
Note 5:
Timing specifications are sample tested at +25°C to ensure compliance. All input control signals are specified with
t
r
= t
f
= 20ns (10% to 90% of +5V) and timed from a voltage level of 1.6V.
Note 6:
t
3
and t
6
are measured with the load circuits of Figure 1 and defined as the time required for an output to cross 0.8V or 2.4V.
Note 7:
t
7
is defined as the time required for the data lines to change 0.5V when loaded with the circuits of Figure 2.

MODE
(MX7576)
Mode Input. MODE = low puts the ADC into its asynchronous conversion mode. MODE has to be
tied high for the synchronous conversion mode and the ROM interface mode.
