General Description

The MAX408/428/448 are high speed general purpose
monolithic operational amplifiers in a single, dual or
quad package, that are useful for signal frequencies
extending into the video range. These Op Amps func­tion in gain configurations greater-than or equal-to 3.
High output current allows large capacitive loads to be
driven at high speeds.

Open-loop voltage gain of 10k V/V and high slew rate of
90V/µs make the MAX408/428/448 ideal for analog
amplification and high speed signal processing. 100MHz
gain bandwidth and a ±0.1% settling time of l50ns make
each amplifier ideal for fast data conversion systems.

The amplifiers are capable of driving back terminated
transmission lines of 75Ω with amplitudes of 5V peak­to-peak.

Along with the high speed and output drive capability,
a 35nA offset current and trimmable offset voltage
make the MAX408/428/448 optimal for signal condition­ing applications where accuracy must be maintained.

ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS—MAX408

(VS= ±5V, TA= +25°C, unless otherwise noted.)

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: Not tested, guaranteed by design.
