DC819A

DC819A demonstration circuit is a jumper definable evaluation platform featuring the LT1990, LT1991, and LT1995 configurable-gain amplifiers. The micropower LT1990 offers high-voltage inputs and selectable difference gains of 1 or 10. The LT1991 is highly flexible micropower general-purpose precision amplifier for gains up to 14. The LT1995 is a high-speed configurable amplifier for gains up to 8. DC819 provides all three of these parts along with signal connectors and jumper fields that allow rapid prototyping and evaluation in various configurations. The DC819 layout includes footprints for TSOT-23-6 and other generic components that may be associated with a more complex evaluation.
