Quad-channel VGA integrates 4 ADC drivers

Designed for PET (positron emission tomography) scanners, communication systems, and advanced video equipment, the AD8264 quad-channel VGA integrates four A/D converter drivers in a 40-pin LFCSP. The device has a 24-dB gain range and features a gain-control interface that provides a precise 20-dB/V linear-in-dB scale.

The part’s pinout provides single-ended output taps directly from the VGAs, which have a –3-dB bandwidth of 235 MHz, and balanced outputs from the 80-MHz output amplifiers. Each channel comprises a high-impedance preamplifier, a high-speed VGA, and a differential output amplifier. Power consumption is 125-mW per channel at ±3.3 V. ($11.95 ea/1,000 — available now.)
