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/√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 guaran-
teed with an output voltage swing of 7.3V
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 vari-
ety 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
