® IVC102 PRECISION SWITCHED INTEGRATOR TRANSIMPEDANCE AMPLIFIER APPLICATIONS DESCRIPTION The IVC102 is a precision integrating amplifier with PRECISION LOW CURRENT MEASUREMENT FET op amp, integrating capacitors, and low leakage PHOTODIODE MEASUREMENTS FET switches. It integrates low-level input current for IONIZATION CHAMBER MEASUREMENTS a user-determined period, storing the resulting voltage CURRENT/CHARGE-OUTPUT SENSORS on the integrating capacitor. The output voltage can be held for accurate measurement. The IVC102 provides LEAKAGE CURRENT MEASUREMENT a precision, lower noise alternative to conventional transimpedance op amp circuits that require a very high value feedback resistor. FEATURES The IVC102 is ideal for amplifying low-level sensor ON-CHIP INTEGRATING
