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 integration 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 40°C to 85°C industrial temperature range.
