The ACF2101BU is a low noise 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 conventional transimpedance amplifier designs and also eliminates the need for high performance, high value feedback resistors. The extremely low bias current and low noise of the ACF2101's Difet® amplifier, along with active laser trimming of both offset and drift, assure precision current to voltage conversion.
