PIN FUNCTIONS

–IN (Pin 1): Inverting Input of Amplifier. Valid input range

is from V– to V+.

VOCM (Pin 2): Output Common Mode Reference Voltage.

The voltage on this pin sets the output common mode

voltage level. If left floating, an internal resistor divider

develops a default voltage of 2.5V with a 5V supply.

V+ (Pin 3): Positive Power Supply. Operational supply

range is 2.8V to 5.25V when V– = 0V.

+OUT (Pin 4): Positive Output Pin. Output capable of

swinging rail-to-rail.

–OUT (Pin 5): Negative Output Pin. Output capable of

swinging rail-to-rail.

V– (Pin 6/Exposed Pad Pin 9): Negative Power Supply,

Typically 0V. Negative supply can be negative as long as

2.8V ≤ (V+ – V–) ≤ 5.25V still holds.

SHDN (Pin 7): When SHDN is floating or directly tied to

V+ the LTC6362 is in the normal (active) operating mode.

When the SHDN pin is connected to V–, the part is disabled

and draws approximately 70µA of supply current.

+IN (Pin 8): Noninverting Input of Amplifier. Valid input

range is from V– to V+.
