Product Introduction

Overview

The AD8330ARQ from Analog Devices Inc. is a wideband variable gain amplifier designed for applications requiring a fully differential signal path, low noise, well-defined gain, and moderately low distortion. This amplifier operates from DC to 150 MHz, making it suitable for a variety of high-frequency applications. It features a linear-in-dB gain control with a range of 0 dB to 50 dB, adjustable via the VDBS pin, and an additional gain control port at the VMAG pin that allows the numeric gain to be varied from 0.03 to 10. The AD8330ARQ is available in 16-lead LFCSP and 16-lead QSOP packages and is specified for operation from −40°C to +85°C.

Q & A

  1. What is the gain range of the AD8330ARQ? The gain range is from 0 dB to 50 dB, controlled by the voltage applied to the VDBS pin.
  2. What is the bandwidth of the AD8330ARQ? The bandwidth is 150 MHz at all gains.
  3. How is the gain controlled in the AD8330ARQ? The gain is controlled via the VDBS pin for linear-in-dB mode and the VMAG pin for linear-in-magnitude mode.
  4. What are the power-down modes available in the AD8330ARQ? The AD8330ARQ has two levels of power-down: fully off and a hibernate mode.
  5. What is the operating temperature range of the AD8330ARQ? The operating temperature range is from −40°C to +85°C.
  6. What are the package types available for the AD8330ARQ? The AD8330ARQ is available in 16-lead LFCSP and 16-lead QSOP packages.
  7. How does the AD8330ARQ handle offset reduction? An external capacitor at Pin OFST sets the high-pass corner of an offset reduction loop, which can be as low as 5 Hz.
  8. What is the typical noise level of the AD8330ARQ at maximum gain? The typical noise level is 5 nV/√Hz at maximum gain.
  9. Can the AD8330ARQ be used in single-ended applications? Yes, the input pins can also be driven from a single-ended source.
  10. What is the typical supply current of the AD8330ARQ? The typical supply current is 20 mA at VS of 2.7 V to 6 V.
