GENERAL DESCRIPTION

The AD8264 is a 4-channel, linear-in-dB, general-purpose

variable gain amplifier (VGA) with a preamplifier (preamp),

and a flexible differential output buffer. Intended for a broad

range of applications, dc coupling combined with wide band-

width makes this amplifier a very good pulse processor.

The gain of each channel is adjusted independently, and all

channels are referenced to a single pin, GNLO. Combined with

a multi-output, digital-to-analog converter (DAC), each section

of the AD8264 can be used for active calibration or as a trim

amplifier.

Each channel includes a single-ended input preamp/VGA

section to preserve the wide bandwidth and fast slew rate for low-

distortion pulse applications. A 6 dB differential output buffer

with common-mode and offset adjustments enable direct coupling

to most modern high speed analog-to-digital converters (ADCs),

using the converter reference output for perfect dc matching levels.

The gain range of the VGA section is 24 dB. Operation from

a dual polarity power supply enables amplification of negative

voltage pulses that are generated by current-sinking pulses into

a grounded load, such as is typical of photodiodes or photo-

multiplier tubes (PMT). Delay-free processing of wide-band

video signals is also possible. The differential output amplifier

permits convenient level shifting and interfacing to single-

supply ADCs using the VOCM and OFSx pins.

The −3 dB bandwidth of the preamp/VGA is dc to 235 MHz,

and the bandwidth of the differential driver is 80 MHz. The

floating gain control interface provides a precise linear-in-dB scale

of 20 dB/V and is easy to interface to a variety of external circuits.

The AD8264 is available in a 40-lead, 6 mm × 6 mm LFCSP

with an operating temperature range of −40°C to +105°C.
