ENHANCED PRODUCT FEATURES Supports defense and aerospace applications (AQEC standard) Military temperature range (−55°C to +125°C) Controlled manufacturing baseline 1 assembly/test site 1 fabrication site Enhanced product change notification Qualification data available on request APPLICATIONS Battery-powered instrumentation Power supply control and protection Telecommunications DAC output amplifier ADC input buffer GENERAL DESCRIPTION The OP284-EP is a dual, single-supply, 4.25 MHz bandwidth amplifier featuring rail-to-rail inputs and outputs (RRIO). The OP284-EP is guaranteed to operate from 5 V to 36 V (or ±2.5 V to ±18 V). This amplifier is superb for single-supply applications requiring both ac and precision dc performance. The combination of wide bandwidth, low noise, and precision makes the OP284-EP useful in a wide variety of applications, including filters and instrumentation. and use as an amplifier or buffer for transducers with wide output ranges. Sensors requiring a rail-to-rail input amplifier include Hall effect, piezoelectric, and resistive transducers. 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 OP284-EP is specified over the extended industrial temperature range of −55°C to +125°C. The OP284-EP is available in a SOIC surface-mount package. Other applications for this amplifier include portable telecommunications equipment, power supply control and protection, Rev. 0 Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
