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 bandwidth makes this amplifier a very good pulse processor.Each channel includes a single-ended input preamp/VGA section to preserve the wide bandwidth and fast slew rate for lowdistortion 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 -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 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.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 photomultiplier tubes PMT. Delay-free processing of wide-band video signals is also possible. The differential output amplifier permits convenient level shifting and interfacing to singlesupply ADCs using the VOCM and OFSx pins.The AD8264 is available in a 40-lead, 6 mm × 6 mm LFCSP with an operating temperature range of -40°C to +105°C.
