DESCRIPTION
The IVC102 is a precision integrating amplifier with
FET op amp, integrating capacitors, and low leakage
FET switches. It integrates low-level input current for
a user-determined period, storing the resulting voltage
on the integrating capacitor. The output voltage can be
held for accurate measurement. The IVC102 provides
a precision, lower noise alternative to conventional
transimpedance op amp circuits that require a very
high value feedback resistor.
The IVC102 is ideal for amplifying low-level sensor
currents from photodiodes and ionization chambers.
The input signal current can be positive or negative.
TTL/CMOS-compatible timing inputs control the inte-
gration period, hold and reset functions to set the
effective transimpedance gain and to reset (discharge)
the integrator capacitor.
Package options include 14-Pin plastic DIP and SO-14
surface-mount packages. Both are specified for the
鈥?0擄C to 85擄C industrial temperature range.
