SPECIFICATIONS
FEATURES
The C7319 which furnishes current-to-voltage conversion
circuit is designed for use with current sources like photo-
multiplier tubes.
The C7319 has three switchable conversion ratios; 0.1, 1
and 10 V/µA and also has two switchable bandwidth selec-
tions.
The performances are convenient to such an application as
requiring a low noise and high gain preamplifier.
