3 Description
The OPA3S328 is a precision, low-voltage,
CMOS operational amplifier (op amp) with
integrated switches that are optimized for flexible
transimpedance applications. Low input bias current
and low input capacitance allows for high-frequency
transimpedance gains at low photocurrent operation
(< 1 nA). The integrated switches, low offset, and
rail-to-rail output performance of the OPA3S328
enable high accuracy across multiple decades of
current values. Small packages, along with integrated
switches, allow for selectable transimpedance
gains and help reduce size for space-constrained
applications.
The OPA3S328 features zero-crossover input
technology, giving the flexibility for the input commonmode
range to span the full supply range without
offset deviations. The device provides enable-disable
capability to allow for portable, handheld applications
in test and measurement. When disabled, the
OPA3S328 output impedance is typically 100 GΩ,
allowing for wired-OR applications using multiple
transimpedance channels.
