Pin Descriptions and Equivalent Circuits
Pin No. Symbol Equivalent Circuit Description
ANALOG I/O
2 V
IN+
Non-Inverting analog signal Input. With a 2.0V reference
voltage, the ground-referenced input signal level is 2.0 V
P-P
centered on V
CM
.
3 V
IN−
Inverting analog signal Input. With a 2.0V reference voltage
the ground-referenced input signal level is 2.0 V
P-P
centered
on V
CM
. This pin may be connected to V
CM
for single-ended
operation, but a differential input signal is required for best
performance.
1 V
REF
Reference input. This pin should be bypassed to AGND with
a 0.1 µF monolithic capacitor. V
REF
is 2.0V nominal and
should be between 1.0V to 2.4V.
31 V
RP
These pins are high impedance reference bypass pins.
Connect a 0.1 µF capacitor from each of these pins to AGND.
DO NOT LOAD these pins.
32 V
RM
30 V
RN
DIGITAL I/O
10 CLK
Digital clock input. The range of frequencies for this input is
100 kHz to 15 MHz (typical) with guaranteed performance at
10 MHz. The input is sampled on the rising edge of this input.
11 OE
OE is the output enable pin that, when low, enables the
TRI-STATE ® data output pins. When this pin is high, the
outputs are in a high impedance state.
8 PD
PD is the Power Down input pin. When high, this input puts
the converter into the power down mode. When this pin is
low, the converter is in the active mode.
