CONT ROL
Control Input. With this pin at 0 V, the SCLK is noncontinuous; with this pin at –5 V, the SCLK
is continuous.
Convert Start. A low to high transition on this input puts the track/hold into the hold mode. T his
input is asynchronous to the CLK .
Clock Input. An external T T L-compatible clock may be applied to this input. Alternatively, tying
this pin to V
SS
, enables the internal laser-trimmed oscillator.
T his is an active low three-state output that provides a framing pulse for serial data. An external
4.7 k
pull-up resistor is required on
SSTRB
.
Serial Clock. SCLK is the gated serial clock output derived from the internal or external ADC
clock. If the 14/
8
/CLK input is at –5 V, then the SCLK runs continuously. With CONT ROL
at 0 V, it is gated off (three-state) after serial transmission is complete. SCLK is an open-drain
output and requires an external 2 k
pull-up resistor.
Serial Data. T his is the three-state serial data output used in conjunction with SCLK and
SSTRB
in
serial data transmission. Serial data is valid on the falling edge of SCLK , when
SSTRB
is low. An
external 4.7 k
pull-up resistor is required on SDAT A.
No Connect.
Digital Ground. Ground return for digital circuitry.

No Connect.
Decoupling point for on-chip reference. Connect 10 nF capacitor between this pin and AGND.
Analog Ground. Ground reference for analog circuitry.
Voltage Reference Output. T he internal 3 V reference is provided at this pin. T he external load
capability is 500

Analog Input. T he input range is
±
