C7319
The C7319 which furnishes current-to-voltage conversion
circuit is designed for use with current sources like
photomultiplier tubes.
The C7319 has three switchable conversion ratios; 10⁵,
10⁶ and 10⁷ volts per ampere and also has two switchable
bandwidth selections.
The performances are convenient to such an application
as reqiuring a low noise and high gain preamplifier.
