Overview

® ACF2101 FPO Low Noise, Dual SWITCHED INTEGRATOR FEATURES q INCLUDES INTEGRATION CAPACITOR, RESET AND HOLD SWITCHES, AND OUTPUT MULTIPLEXER q LOW NOISE: 10µVrms q LOW CHARGE TRANSFER: 0.
1pC q WIDE DYNAMIC RANGE: 120dB q LOW BIAS CURRENT: 100fA APPLICATIONS q CURRENT TO VOLTAGE CONVERSION q PHOTODIODE INTEGRATOR q CURRENT MEASUREMENT q CHARGE MEASUREMENT q CT SCANNER FRONT END q MEDICAL, SCIENTIFIC, AND INDUSTRIAL INSTRUMENTATION DESCRIPTION The ACF2101 is a dual switched integrator for precision applications.
Each channel can convert an input current to an output voltage by integration, using either an internal or external capacitor.
Included on the chip are precision 100pF integration capacitors, hold and reset switches, and output multiplexers.
As a complete circuit on a single chip, the ACF2101 eliminates many of the problems commonly encountered in discrete designs, such as leakage current errors and noise pickup.
The integrating approach can provide lower noise than convent...
