Overview

  • Voltage Noise: 2.4nV per root-Hz (max) at 1kHz
  • 2.5mA Supply Current Per Amplifier
  • Low Supply Voltage Operation: ±2.4V to ±5V
  • 28MHz Unity-Gain Bandwidth
  • 4.5V/µs Slew Rate
  • 250µV (max) Offset Voltage (MAX410/MAX412)
  • 115dB (min) Voltage Gain
  • Available in an Ultra-Small TDFN Package

The MAX410/MAX412/MAX414 single/dual/quad op amps set a new standard for noise performance in high-speed, low-voltage systems. Input voltage-noise density is guaranteed to be less than 2.4nV per root-Hz at 1kHz. A unique design not only combines low noise with ±5V operation, but also consumes 2.5mA supply current per amplifier. Low-voltage operation is guaranteed with an output voltage swing of 7.3VP-P into 2kΩ from ±5V supplies. The MAX410/MAX412/MAX414 also operate from supply voltages between ±2.4V and ±5V for greater supply flexibility.

Unity-gain stability, 28MHz bandwidth, and 4.5V/µs slew rate ensure low-noise performance in a wide variety of wideband and measurement applications. The MAX410/MAX412/MAX414 are available in DIP and SO packages in the industry-standard single/dual/quad op amp pin configurations. The single comes in an ultra-small TDFN package (3mm x 3mm).
