Jumpers
JP1 – Sets the DC bias for V
internally biased or externally driven. The voltage on this
pin sets the output common mode voltage level. V
is the default setting.
JP2 – Toggles the LTC6362 On and Off. Part On (5V) is
the default setting.
JP3 – In the REF position the Digital Gain Compression
is off and the analog input range at ADC inputs is 0V to
V . In the GND position Digital Gain Compression is
REF
turned on and the analog input range at ADC inputs is
0.1V to 0.9V .

JP4 – Ties the WP pin to V
write-protect pin. If tied to V
is enabled. If WP is tied to GND, the hardware write-
protection is disabled.
JP5 – VCCIO sets the output levels at J3 to either 3.3V
or 2.5V. Use 3.3V to interface to the DC718 which is the
default setting.
