LT1997 – Configurable Precision Amplifier

产品详情

Demonstration Circuit 2551A is a Configurable Precision Amplifier featuring the LT1997.

The DC2551A-C supports the LT1997-1 version.

This demo board provides a rapid evaluation tool with jumpers providing the typical interconnection options that facilitate setting the pin-strapped internal gain configuration. The LT1997 is unusual in that it may be powered from a low voltage (down to 3.3V) while it accepts sign particularly high supply voltages, up to 50V. Connection points are provided to wire the amplifier in other configurations besides those possible with the jumpers alone.
