Description
General part information
OPA858 Series
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 closed-loop bandwidths at transimpedance gains in the tens to hundreds of kΩs range.
The graph below demonstrates the bandwidth and noise performance of the OPA858 as a function of the photodiode capacitance when the amplifier is configured as a TIA. The total noise is calculated over a bandwidth range extending from DC to the calculated f-3dBfrequency on the left-hand scale. The OPA858 package features a feedback pin (FB) that simplifies the feedback network connection between the input and the output.
The OPA858 is optimized for use in optical Time-of-Flight (ToF) systems like the one shown in the figure below where the OPA858 is used with theTDC7201time-to-digital converter. The OPA858 can be used in high-resolution LIDAR systems with a high-speed analog-to-digital converter (ADC) and a differential output amplifier like theTHS4541orLMH5401to drive the ADC.
