THS4021

THS4021, THS4022 SLOS265E – AUGUST 1999 – REVISED MARCH 2024 THS402x 2GHz, 10V/V Stable, Low-Noise, High-Speed Amplifiers 1 Features 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 2 Applications Ultrasound scanner Source measurement unit (SMU) Power quality meter 3 Description 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 dualamplifier 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.
