Zero-Drift Operational Amplifiers
Demonstration circuit 2837A is a customizable
board showcasing the micropower zero-drift op amp
LTC
®
2063 (-A option) or LTC2066 (-B option) with shut-
down in an SC70 6-pin package. The board is laid out for
most common op amp applications and left mostly unstuffed
to maximize flexibility for a wide range of applications.
The DC2837A includes the SC70 package op amp, jump-
ers, unity gain configuration resistors, input lowpass fil-
ters, reverse supply protection, and supply bypass capaci-
tors on a small printed circuit board with turrets and SMA All registered trademarks and trademarks are the property of their respective owners.
PERFORMANCE SUMMARY
connectors for input, output, power and shutdown. The
board may be used in split rail or single supply as desired.
The user only needs to furnish external ±2.5V split sup-
plies and an input signal to operate the board. An external
shutdown signal can be applied as well to demonstrate
the very minimal transient current when starting up the
part from shutdown.
Design files for this circuit board are available .
