ANALOG DEVICES AD8332ACPZ 可编程/可变增益放大器, 2 放大器, 2个放大器, 100 MHz, -40 °C, 85 °C, 4.5V 至 5.5V
The 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.
