Analog Input.
Analog Input.
Analog Ground.
Voltage Reference Input. T his is normally tied to V
DD
.
Chip Select. Active Low Logic input. T he device is selected when this input is active.
Convert Start. A low to high transition on this input puts the track/hold into hold mode and starts con-
version. T his input is asynchronous to the CLK IN and is independent of
CS
and
RD
.
Read. Active Low Logic Input. T his input is used in conjunction with
CS
low to enable data outputs.
Active Low Logic Output. T his status line indicates converter status.
BUSY
is low during conversion.
Clock Input. T T L-compatible logic input. Used as the clock source for the A/D converter. T he mark/
space ratio of the clock can vary from 40/60 to 60/40.
Digital Ground.
DB0–DB11 T hree-State Data Outputs. T hese become active when
CS
and
RD
are brought low.
MODE
MODE Input. T his input is used to put the device into the power save mode (MODE = 0 V). During
normal operation, the MODE input will be a logic high (MODE = V
DD
).
V
DD
Power Supply. T his is nominally +5 V.
