Linear Technology LTC6363 Manual

Description
The LTC 6363 is a low power, low noise differential op amp
®
with rail-to-rail output swing and good DC accuracy. The
amplifier may be configured to process a fully differential
input signal or to convert a single-ended input signal to
a differential output signal. The differential outputs of the
DC2319A can be configured with a first order RC network
for driving the differential inputs of an ADC. The DC2319A

Quick start proceDure
Refer to Figure 1a. Check to ensure that both jumpers, JP1
and JP2, are set as shown. (JP1 to PWR_ON and JP2 to
SINGLE SUPPLY). Power up the DC2319A from a single
+
power supply, V = 5V and GND = 0V. Connect VIN
ground using E8. Connect an input voltage to VIN
E7. The differential output voltage can then be measured
– +
on VOUT and VOUT (E9 and E10). The outputs will be

can be DC-coupled or AC-coupled. Onboard jumpers con-
figure the DC2319A for dual or single power supply. In
addition, there are multiple optional surface-mount pads
that can be used to change the LTC6363 configuration.

level-shifted to be balanced symmetrical around approxi-
mately 2.5V. The difference between the outputs will be
the gain multiplied by the difference between the inputs.
For a similar setup using a split supply, change the setting
of JP2 to DUAL SUPPLY, and connect a negative supply
