transconductance
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 OTA, 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
OTA can be adjusted with an external resistor,
allowing bandwidth, quiescent current, and gain
trade-offs to be optimized.
Also included in the OPA860 is an uncommited
closed-loop,
unity-gain
1600MHz bandwidth and 4000V/μs slew rate.

Used as a basic building block, the OPA860 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
OPA860 is available in an SO-8 surface-mount pack-
age.
