MAXIM MAX410, MAX412, MAX414 User Manual

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 guaran­teed with an output voltage swing of 7.3V

P-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 ultra­small TDFN package (3mm ✕ 3mm).

ABSOLUTE MAXIMUM RATINGS

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1: The amplifier inputs are connected by internal back-to-back clamp diodes. In order to minimize noise in the input stage, current-

limiting resistors are not used. If differential input voltages exceeding ±1.0V are applied, limit input current to 20mA.
