Description
General part information
OPA3S328 Series
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 common-mode 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.
