AD604ARSZ

AD604 is an ultralow noise, very accurate, dual-channel, linear-in-dB variable gain amplifier (VGA) optimized for time- based variable gain control in ultrasound applications; however, it supports any application requiring low noise, wide bandwidth, variable gain control. Typical application includes ultrasound and sonar time-gain controls, high performance AGC systems and signal measurement.

• Ultralow input noise at maximum gain is 0.80nV/√Hz, 3.0pA/√Hz
• 2 independent linear-in-dB channels
• Absolute gain range per channel programmable: 0dB to 48dB (preamplifier gain = 14dB)
• 0dB to 48dB (preamplifier gain = 14dB) through 6dB to 54dB (preamplifier gain = 20dB)
• ±1dB gain accuracy, 40MHz (-3dB) bandwidth and 300Kohm input resistance
• Variable gain scaling of 20dB/V through 40dB/V
• Stable gain with temperature and supply variations
• Single-ended unipolar gain control
• Power shutdown at lower end of gain control and drive ADCs directly
• 24 lead SSOP package, operating temperature range from -40 to 85°C
