DEMO MANUAL DC2319A
JP1:
Jumper toggles the LTC6363 between SHDN and
PWR ON.
JP2:
Jumper toggles the SUPPLY between DUAL and
SINGLE power supplies. If set to dual supply, connect a
negative supply voltage to V
–
.
V
+
:
Connect to Positive Power Supply.
GND:
Connect to Ground. Available at multiple turrets
on the board, all shorted together internally. Only need
to connect one, others can be used as ground point for
measurements.
V
–
:
Negative Power Supply Voltage. No need to connect
if JP2 is set to single supply.
EXT SHDN:
Externally Drives the SHDN Pin. No need to
connect. To turn the amplifier ON and OFF with a logic
signal, remove JP1 (or set to the PWR ON position) and
then connect an external logic signal here to EXT SHDN.
(See LTC6363 data sheet for logic levels)
EXT VOCM:
Externally Drives the VOCM Pin. The voltage
on this pin sets the output common mode voltage level.
If left floating (default setting), then an internal resistor
divider develops a voltage that is approximately mid-way
between the LTC6363 V

supply rails.
VIN
+
:
Connect noninverting input signal to the amplifier
circuit. Available as SMA connector J1 and as turret E7.
VIN
–
:
Connect inverting input signal to the amplifier circuit.
Available as SMA connector J2 and as turret E8.
VOUT
–
:
Measure inverting output signal from the amplifier
circuit. Available as SMA connector J3 and as turret E9.
VOUT
+
:
Measure noninverting output signal from the
amplifier circuit. Available as SMA connector J4 and as
turret E10.
