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.
