GENERAL DESCRIPTION
The AD8337 is a low noise, single-ended, linear-in-dB, general-
purpose variable gain amplifier (VGA) usable at frequencies
from dc to 100 MHz; the 3 dB bandwidth is 280 MHz.
Excellent bandwidth uniformity across the entire gain range
and low output-referred noise makes the AD8337 ideal for
gain trim applications and for driving high speed analog-to-
digital converters (ADCs).
Excellent dc characteristics combined with high speed make the
AD8337 particularly suited for industrial ultrasound, PET
scanners, and video applications. Dual-supply operation enables
gain control of negative-going pulses, such as those generated
by photodiodes or photomultiplier tubes.
The AD8337 uses the popular and versatile X-AMP architecture,
exclusively from Analog Devices, Inc., with a gain range of 24 dB.
The gain control interface provides precise linear-in-dB scaling
of 19.7 dB/V, referenced to VCOM.
The AD8337 includes an uncommitted operational current-
feedback preamplifier (PrA) that operates in inverting or
noninverting configurations. Using external resistors, the device
can be configured for gains of 6 dB or greater. The AD8337 is
characterized by a noninverting PrA gain of 2× using two external
100 Ω resistors. The attenuator has a range of 24 dB, and the
output amplifier has a fixed gain of 8× (18.06 dB). The lowest
nominal gain range is 0 dB to 24 dB and can be shifted up or down
by adjusting the preamp gain. Multiple AD8337 devices can be
connected in series for larger gain ranges, interstage filtering to
suppress noise and distortion, and nulling offset voltages.
The operating temperature range of the AD8337 is 40°C to
+85°C, and is available in an 8-lead, 3 mm × 3 mm LFCSP.
