The NE/SA5234 is a unique low-voltage quad operational amplifier
specifically designed to operate in a broadly diverse environment. It
is an enhanced pin-for-pin replacement for the LM324 category of
devices. Supply conditions can range from 1.8V to 6.0V with a
resultant current drain of 2.8mA,-700μA per op amp.
Most notable are the input and output dynamic range characteristics
of the individual op amps. The common-mode input voltage can
actually exceed the positive and negative supply rails by 250mV
with no danger of output latching or polarity reversal. In addition, the
output of each op amp will swing to within 50mV of the supply rails
over the full supply range.
The frequency related characteristics are also above average for
low voltage devices in this class. Internal unity gain compensation
makes the NE5234 very resistant to any tendency to oscillate in low
closed-loop gain configurations. Even so, a unity-gain bandwidth of
2.5MHz is retained. Slew rate is 0.8V/μs and each op amp will settle
to a 1% of nominal level within 1.4μs.
