  • Ultra-low 1.2nV/√Hz voltage noise
  • High speed:
    • 100MHz bandwidth [G = 2 (–1), –3dB]
    • 100V/µs slew rate
  • Very low distortion
    • THD = –81dBc (f = 1MHz, RL = 150Ω)
    • THD = –96dBc (f = 1MHz, RL = 1kΩ)
  • Low 0.3mV (typical) input offset voltage
  • 200mA output current drive (typical)
  • Typical operation from ±4.5V to ±16V
  • Offset nulling pins on the THS4031

The THS4031 and THS4032 (THS403x) are ultra-low voltage noise, high-speed voltage feedback amplifiers that are an excellent choice for applications requiring low voltage noise, including communications and imaging. The single-amplifier THS4031 and the dual-amplifier THS4032 offer very good ac performance with 100MHz bandwidth (G = 2), 100V/µs slew rate, and 70ns settling time (0.1%). The THS403x are unity-gain stable with 120MHz bandwidth. These amplifiers have a high drive capability of 200mA and draw only 7.5mA supply current per channel. With –96dBc of total harmonic distortion (THD) at f = 1MHz and a very low noise of 1.2nV/√Hz, the THS403x are designed for applications requiring low distortion and low noise such as buffering analog-to-digital converters.
