Precision Rail-to-Rail Input and Output Operational Amplifiers OP184/OP284/OP484 FEATURES PIN CONFIGURATIONS Single-supply operation Wide bandwidth: 4 MHz Low offset voltage: 65 μV Unity-gain stable High slew rate: 4.0 V/ μs Low noise: 3.9 nV/√Hz DNC OP184 NC V+ 6 2 8 7 1 –IN A OUT A 5 DNC – +IN A 3 V– 4 TOP VIEW (Not to Scale) 00293-001 + NOTES 1. NC = NO CONNECT 2.

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. 6 –IN B 4 5 +IN B TOP VIEW (Not to Scale) Figure 2. 8-Lead PDIP (P-Suffix) 8-Lead SOIC (S-Suffix) OUT A 1 14 OUT D –IN A 2 13 –IN D +IN A 3 12 +IN D V+ 4 11 V– +IN B 5 10 +IN C –IN B 6 9 –IN C OUT B 7 8 OUT C OP484 TOP VIEW (Not to Scale) 00293-003 The OP184/OP284/OP484 are single, dual, and quad single-supply, 4 MHz bandwidth amplifiers featuring rail-to-rail inputs and outputs. They are guaranteed to operate from 3 V to 36 V (or ±1.5 V to ±18 V). 7 3 V– GENERAL DESCRIPTION 2 +IN A 00293-002 Battery-powered instrumentation Power supply control and protection Telecommunications DAC output amplifier ADC input buffer Figure 3. 14-Lead PDIP (P-Suffix) 14-Lead Narrow-Body SOIC (S-Suffix) The ability to swing rail-to-rail at both the input and output enables designers to build multistage filters in single-supply systems and to maintain high signal-to-noise ratios. The OP184/OP284/OP484 are specified over the hot extended industrial temperature range of −40°C to +125°C. The single OP184 is available in 8-lead SOIC surface mount packages. The dual OP284 is available in 8-lead PDIP and SOIC surface mount packages. The quad OP484 is available in 14-lead PDIP and 14-lead, narrow-body SOIC packages. Table 1.
