Wide Bandwidth (80MHz, Open-Loop, G = +5)  
The OPA861 is a versatile monolithic component  
designed for wide-bandwidth systems, including high  
performance video, RF and IF circuitry. The OPA861  
is a wideband, bipolar operational transconductance  
amplifier (OTA).  
High Slew Rate (900V/µs)  
High Transconductance (95mA/V)  
External IQ-Control  
Low Quiescent Current (5.4mA)  
The OTA or voltage-controlled current source can be  
viewed as an ideal transistor. Like a transistor, it has  
three terminals—a high impedance input (base), a  
low-impedance input/output (emitter), and the current  
output (collector). The OPA861, however, is  
self-biased and bipolar. The output collector current is  
zero for a zero base-emitter voltage. AC inputs  
centered about zero produce an output current, which  
is bipolar and centered about zero. The  
transconductance of the OPA861 can be adjusted  
with an external resistor, allowing bandwidth, quiesc-  
ent current, and gain trade-offs to be optimized.

Video/Broadcast Equipment  
Communications Equipment  
High-Speed Data Acquisition  
Wideband LED Drivers  
Control Loop Amplifiers  
Wideband Active Filters  
Line Drivers  
Used as a basic building block, the OPA861 sim-  
plifies the design of AGC amplifiers, LED driver  
circuits for fiber optic transmission, integrators for fast  
pulses, fast control loop amplifiers and control ampli-  
fiers for capacitive sensors and active filters. The  
OPA861 is available in SO-8 and SOT23-6 sur-  
face-mount packages.
