Description

Demonstration circuit 1979A is a high voltage CMOS amplifier featuring the LTC®6090. An onboard isolated flyback converter provides ±62V power to the LTC6090 for evaluating large signal performance. A jumper sets the gain of the ultrahigh-input impedance circuit to either unity (1×) or 20×. In the 20× mode, a signal input of just 3V can provide nearly full-swing output. In the unity-gain setting, the part operates as a precision buffer for highvoltage signals.

SPECIAL FORM-FACTOR

The DC1979A includes a preassembled power converter and amplifier circuit on a small printed circuit, so the user only needs to furnish a 7V to 12V power source to operate the demo. The layout has provisions for optional BNC connectors and mounting features to install the board in a standard plastic enclosure if a permanent utility unit is desired. Refer to the Appendix for mechanical details.
