The AD8332ARUZ is an ultralow noise linear-in-dB Variable Gain Amplifier (VGA) optimized for ultrasound systems, it is usable as a low noise variable gain element at frequencies up to 120MHz. Included in each channel are an ultralow noise preamp (LNA), an X-AMP® VGA with 48dB of gain range and a selectable gain postamp with adjustable output limiting. The LNA gain is 19dB with a single-ended input and differential outputs. Using a single resistor, the LNA input impedance can be adjusted to match a signal source without compromising noise performance. The 48dB gain range of the VGA makes these devices suitable for a variety of applications. Excellent bandwidth uniformity is maintained across the entire range. The gain control interface provides precise linear-in-dB scaling of 50dB/V for control voltages between 40mV and 1V. Factory trim ensures excellent part-to-part and channel-to-channel gain matching.
● Active input impedance matching
● 145mW/channel Low power
● 48nV/√Hz Typical low output-referred noise
● Single 5V supply operation
