OPA858 Overview
The OPA858 is a wideband, low-noise, operational amplifier with CMOS inputs for wideband transimpedance and voltage amplifier applications. When the device is configured as a transimpedance amplifier (TIA), the 5.5-GHz gain bandwidth product (GBWP) enables applications requiring high closedloop bandwidths at transimpedance gains in the tens to hundreds of kΩs range. The graph below demonstrates the bandwidth and...
