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 func-
tion 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/s 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 75
with amplitudes of 5V peak-
to-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 condition-
ing applications where accuracy must be maintained.
