1. NC = NO CONNECT
2. DNC = DO NOT CONNECT APPLICATIONS Figure 1. 8-Lead SOIC (S-Suffix) GENERAL DESCRIPTION These amplifiers are superb for single-supply applications requiring
both ac and precision dc performance. The combination of wide
bandwidth, low noise, and precision makes the OP184/OP284/
OP484 useful in a wide variety of applications, including filters
and instrumentation.
Other applications for these amplifiers include portable telecommunications equipment, power supply control and protection,
and use as amplifiers or buffers for transducers with wide output
ranges. Sensors requiring a rail-to-rail input amplifier include
Hall effect, piezoelectric, and resistive transducers. 1 OP284 8 V+
