Texas Instruments OPA3S328 CMOS Op-Amps offer precision, low-voltage, and low-input bias-current in a small package. The device provides integrated switches that are optimized for flexible transimpedance applications. The OPA3S328 features low input bias current and low input capacitance, enabling high-frequency transimpedance gains at low photocurrent operation (< 1nA).
The TI OPA3S328 CMOS Op-Amps compiles integrated switches, low offset, and rail-to-rail output performance to enable high accuracy across multiple decades of current values. A small package and integrated switches allow the OPA3S328 to access selectable transimpedance gains and help reduce size for space-constrained applications.
The zero-crossover input technology featured on the device permits the flexibility for the input common-mode range to span the entire supply range without offset deviations. The OPA3S328 provides the enable-disable capability to allow for portable, handheld applications in test and measurement. When disabled, the OPA3S328 output impedance is typically 100GΩ, allowing for wired-OR applications using multiple transimpedance channels.
