OPA859/OPA859-Q1 Wideband Low-Noise Op Amps

Texas Instruments OPA859/OPA859-Q1 Wideband Low-Noise Operational Amplifier comes with CMOS inputs for wideband transimpedance and voltage amplifier applications. When the device is configured as a transimpedance amplifier (TIA), the 0.9GHz gain bandwidth product (GBWP) enables high closed-loop bandwidths in low-capacitance photodiode applications.
