DC-coupled
Single-ended input and differential output
Supplies: ±2.5 V to ±5 V
Low power: 140 mW per channel at ±3.3 V The AD8264 is a quad, linear-in-dB, general-purpose, variable
gain amplifier (VGA) with a preamplifier (preamp), and a flexible
differential output buffer. 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 low distortion pulse applications. A 6 dB differential output buffer with
common-mode and offset adjustments enable direct coupling to …
