DESCRIPTION
The OPA660 is a versatile monolithic component
designed for wide-bandwidth systems including high
performance video, RF and IF circuitry. It includes a
wideband, bipolar integrated voltage-controlled cur-
rent source and voltage buffer amplifier.
The voltage-controlled current source or Operational
Transconductance Amplifier (OTA) 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 current is zero-for-zero dif-
ferential input voltage. AC inputs centered about zero
produce an output current which is bipolar and cen-
tered 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.
The open-loop buffer amplifier provides 850MHz
bandwidth and 3000V/
μ
s slew rate. Used as a basic
building block, the OPA660 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 OPA660 is packaged in SO-8 surface-mount,
and 8-pin plastic DIP, specified from –40
