9 Detailed Description
9.1 Overview
The ultra-wide, 5.5-GHz gain bandwidth product (GBWP) of the OPA858, combined with the broadband voltage
noise of 2.5 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 OPA858 combines multiple features to optimize dynamic performance. In addition to the wide, small-signal
bandwidth, the OPA858 has 600 MHz of large signal bandwidth (VOUT = 2 VPP) and a slew rate of 2000 V/µs.
The OPA858 is offered in a 2-mm × 2-mm, 8-pin WSON package that features a feedback (FB) pin for a simple
feedback network connection between the amplifiers output and inverting input. Excess capacitance on an
amplifiers input pin can reduce phase margin causing instability. This problem is exacerbated in the case of very
wideband amplifiers like the OPA858. To reduce the effects of stray capacitance on the input node, the OPA858
pinout features an isolation pin (NC) between the feedback and inverting input pins that increases the physical
spacing between them thereby reducing parasitic coupling at high frequencies. The OPA858 also features a very
low capacitance input stage with only 0.8-pF of total input capacitance.
9.2 Functional Block Diagram
The OPA858 is a classic, voltage feedback operational amplifier (op amp) with two high-impedance inputs and a
low-impedance output. Standard application circuits are supported, like the two basic options shown in Figure 46
and Figure 47. The DC operating point for each configuration is level-shifted by the reference voltage (VREF),
which is typically set to midsupply in single-supply operation. VREF is typically connected to ground in split-supply
application
