  • Ultra-low 1.2nV/√Hz voltage noise
  • High speed:
    • 2GHz gain-bandwidth product
    • 470V/µs slew rate
    • 30ns settling time (0.1%)
  • Stable at gains ≥10V/V
  • Output drive, IO = 200mA (typical)
  • Very low distortion:
    • THD = –68dBc (f = 1MHz, RL = 150Ω)
  • Wide range of power supplies:
    • VCC = ±4.5V to ±16V
  • Offset nulling pins on the THS4021

The THS4021 and THS4022 (THS402x) are ultra-low voltage noise, high-speed voltage-feedback amplifiers that are an excellent choice for applications requiring low voltage noise, including communication and imaging. The single-amplifier THS4021 and the dual-amplifier THS4022 offer very good ac performance with a 290MHz closed-loop bandwidth, 470V/µs slew rate, and 30ns settling time (0.1%) for a gain of 10V/V. The THS402x are stable at gains of 10V/V or greater and –9V/V or less. These amplifiers have a high drive capability of 200mA and draw only 7.5mA of supply current per amplifier. With a total harmonic distortion (THD) of –68dBc at f = 1MHz, the THS402x are designed for applications requiring low distortion.
