Product Overview

AD8331 is a single channel, ultralow noise linear-in-dB, variable gain amplifier (VGA). The 48dB gain range of the VGA makes this device 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. Differential signal paths result in superb second- and third order distortion performance and low crosstalk. It is widely used in application such as ultrasound and sonar time-gain controls, high performance automatic gain control (AGC) systems, I/Q signal processing, high speed, dual ADC drivers etc.
  • Voltage noise is 0.74nV/√Hz, slew rate is 650V/µs
  • Current noise is 2.5pA/√Hz
  • 3dB bandwidth is 120MHz
  • Low power is 125mW/channel
  • Wide gain range with programmable postamp
  • −4.5dB to +43.5dB in LO gain mode, 7.5dB to 55.5dB in HI gain mode
  • Low output-referred noise is 48nV/√Hz typ, single 5V supply operation
  • Active input impedance matching, selectable output clamping level
  • Operating temperature is –40°C to +85°C, optimized for 10-bit/12-bit ADCs
  • Packaging style is 20-lead shrink small outline package (QSOP)
