PREAMPLIFIER UNIT C7319 PRELIMINARY DATA JUN. 2000 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. FEATURES •• •• 105, 106 and 107 V/A conversion ratios 20 kHz and 200 kHz bandwidth with switch selecting Adjustable offset level with VR included Operatable with wide supply voltage : ±5 V to ±15 V MAXIMUM RATINGS Parameter Value Unit Vdc ±18 0 to +40 Supply Voltage Operating Temperature Storage Temperature -20 to +60 CHARACTERISTICS Conversion Ratio Parameter 105 V/A 106 V/A 107 V/A ± 5 to ±15 ±8 Supply Voltage Supply Current ( at ±15 V ) 105 Current to Voltage Conversion Factor 106 Maximum Output Voltage with no load resistor ( at ±15 V ) 13 Output Voltage with 50 Ω load resistor 2 Maximum Input Signal Current ( at ±15 V ) 130 Frequency Bandwidth (-3 dB) Input Polarity Amplifying Method Output Impedance Equivalent Noise Input (rms) 13 Vdc mA Typ. 107 1.3 V µA 0 to 20 or 0 to 200 * kHz Typ.
