DESCRIPTION
The ACF2101 is a dual switched integrator for preci-
sion 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 encoun-
tered in discrete designs, such as leakage current errors
and noise pickup. The integrating approach can pro-
vide 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
amplifiers, along with active la-
ser trimming of both offset and drift, assure precision
current to voltage conversion.
Although designed for +5V, –15V supplies, the
ACF2101 can be operated on supplies up to
±
18VDC.
It is available in both 24-pin plastic DIP and SOIC
packages.
