9.1 Overview

The ultra-wide, 8-GHz gain bandwidth product (GBWP) of the OPA855, combined with the broadband voltage noise of 0.98 nV/√Hz, produces a viable amplifier for wideband transimpedance applications, high-speed data acquisition systems, and applications with weak signal inputs that require low-noise and high-gain front ends. The OPA855 combines multiple features to optimize dynamic performance. In addition to the wide, small-signal bandwidth, the OPA855 has 850 MHz of large-signal bandwidth (2 VPP), and a slew rate of 2750 V/µs, making the device a viable option for high-speed pulsed applications.
