OTA FEATURES

DESCRIPTION

•

Wide Bandwidth (80MHz, Open-Loop, G = +5)

The OPA860 is a versatile monolithic component

designed for wide-bandwidth systems, including high

performance video, RF and IF circuitry. It includes a

wideband, bipolar operational transconductance

amplifier (OTA), and voltage buffer amplifier.

•

High Slew Rate (900V/µs)

High Transconductance (95mA/V)

External I_Q-Control

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.

BUFFER FEATURES

•

Closed-Loop Buffer

Wide Bandwidth (1600MHz, V_O= 1V_PP

Low Quiescent Current (11.2mA)

•

Versatile Circuit Function

APPLICATIONS

Also included in the OPA860 is an uncommited

closed-loop, unity-gain buffer. This provides

1600MHz bandwidth and 4000V/µs slew rate.

OPA660 Upgrade

Used as

a basic building block, the OPA860

simplifies the design of AGC amplifiers, LED driver

circuits for fiber optic transmission, integrators for fast

pulses, fast control loop amplifiers and control

amplifiers for capacitive sensors and active filters.

The OPA860 is available in an SO-8 surface-mount

package.
