AD8264ACPZ

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 6dB differential output buffer with common-mode and offset adjustments enable direct coupling to most modern high speed analogue-to-digital converters (ADCs), using the converter reference output for perfect DC matching levels. Typical application includes multi channel data acquisition, positron emission tomography, gain trim, industrial and medical ultrasound and radar receivers.

• Low noise: 2.3nV/ √Hz voltage noise and 2pA/ √Hz current noise
• Wide BW: small signal: 235MHz (VGAx); 80MHz (output amplifier) and large signal: 80MHz (1V p-p)
• Gain range: 0 to 24dB (input to VGA output) and 6 to 30dB (input to differential output)
• Gain scaling of 20dB/V
• DC-coupled
• Single -ended input and differential output
• Dual supply range from ±2.5V to ±5V
• Low power: 140mW per channel at ±3.3V
• 40 lead LFCSP package
• Operating temperature range from -40°C to 85°C
