19-4194; Rev 6; 9/09

Single/Dual/Quad, 28MHz, Low-Noise,

Low-Voltage, Precision Op Amps

General Description

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 7.3VP-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 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  3mm).
