PA-9 PREAMPLIFIERS Operating Instructions
■The PA-9 preamplifier is ideal for high-impedance photodiodes such as cryogenically cooled InSb, Ge and InAs. It offers superior high-frequency performance, with low current noise and ultra-low voltage noise. When ordered with a detector, the preamp is matched for maximum gain and sensitivity. Alternatively, the customer may specificy gain and/or minimum required bandwidth. Bandwidth is a function of detector resistance and capacitance as well as preamp gain, as shown on the reverse side of this bulletin.
●Specifications:
■Bandwidth (maximum): DC to 750 KHz
■First Stage Gain: 107, 106 or 105 V/A
■Voltage Noise Density @1 KHz: 6.5 nV Hz -1/2
■Current Noise Density @1 KHz: 0.04 pA Hz -1/2
■Input Offset Voltage: ± 10 mV Typ.
■Input Bias Current: ± 1pA Typ.
■Maximum Output
▲(First Stage): 6 V P-P
▲(Second Stage): 10 V P-P
■Power Requirements: ±12VDC or ±15VDC, 20 mA
■Size: 3" x 4.5" x 1"
