DESCRIPTION
The VCA610 is a wideband, continuously variable,
voltage controlled gain amplifier. It provides linear-
dB gain control with high impedance inputs. It is
designed to be used as a flexible gain control element
in a variety of electronic systems.
The VCA610 has a gain control range of 80dB (–40dB
to +40dB) providing both gain and attenuation for
maximum flexibility in a small 8-lead SO-8 or plastic
dual-in-line package. The broad attenuation range can
be used for gradual or controlled channel turn-on and
turn-off for applications in which abrupt gain changes
can create artifacts or other errors. In addition, the
output can be disabled to provide –80dB of attenua-
tion. Group delay variation with gain is typically less
than ±2ns across a bandwidth of 1 to 15MHz.
The VCA610 has a noise figure of 3.5dB (with an RS
of 200) including the effects of both current and
voltage noise. Instantaneous output dynamic range is
70dB for gains of 0dB to +40dB with 1MHz noise
bandwidth. The output is capable of driving 100.
The high speed, 300dB/µs, gain control signal is a
unipolar (0 to –2V) voltage that varies the gain lin-
early in dB/V.
APPLICATIONS
q OPTICAL DISTANCE MEASUREMENT
q AGC AMPLIFIER
q ULTRASOUND
q SONAR
q ACTIVE FILTERS
q LOG AMPLIFIER
q IF CIRCUITS
q CCD CAMERAS
The VCA610 is designed with a very fast overload
recovery time of only 200ns. This allows a large
signal transient to overload the output at high gain,
without obscuring low-level signals following closely
behind. The excellent overload recovery time and
distortion specifications optimize this device for low-
level doppler measurements.
