NE531 Datasheet, PDF (1/8 Pages) NXP Semiconductors – High slew rate operational amplifier

Philips Semiconductors Linear Products
High slew rate operational amplifier
Product specification
NE/SE531
DESCRIPTION
The 531 is a fast slewing high performance operational amplifier
which retains DC performance equal to the best general purpose
types while providing far superior large-signal AC performance. A
unique input stage design allows the amplifier to have a large-signal
response nearly identical to its small-signal response. The amplifier
is compensated for truly negligible overshoot with a single capacitor.
In applications where fast settling and superior large-signal
bandwidths are required, the amplifier out-performs conventional
designs which have much better small-signal response. Also,
because the small-signal response is not extended, no special
precautions need be taken with circuit board layout to achieve
stability. The high gain, simple compensation, and excellent stability
of this amplifier allow its use in a wide variety of instrumentation
applications.
FEATURES
• 35V/µs slew rate at unity gain
• Pin-for-pin replacement for µA709, µA748, or LM101
• Compensated with a single capacitor

NOTES:
1. The following derating factors should be applied above 25°C:
FE package at 6.2mW/°C
N package at 9.3mW/°C
2. For supply voltages less than ±15V, the absolute maximum input voltage is equal to the supply voltage.
3. Short-circuit may be to ground or either supply. Rating applies to +125°C case temperature or to +75°C ambient temperature.
