ADA4084-1

Data Sheet 30 V, Low Noise, Rail-to-Rail Input/Output, Low Power Operational Amplifiers ADA4084-1/ADA4084-2/ADA4084-4 FEATURES Rail-to-rail input/output Low power: 0.625 mA typical per amplifier at ±15 V Gain bandwidth product: 15.9 MHz at AV = 100 typical Unity-gain crossover: 9.9 MHz typical −3 dB closed-loop bandwidth: 13.9 MHz typical at ±15 V Low offset voltage: 100 µV maximum (SOIC) Unity-gain stable High slew rate: 4.6 V/µs typical Low noise: 3.9 nV/√Hz typical at 1 kHz Long-term offset voltage drift (10,000 hours): 3 µV typical Temperature hysteresis: 4 µV typical APPLICATIONS Battery-powered instrumentation High-side and low-side sensing Power supply control and protection Telecommunications Digital-to-analog converter (DAC) output amplifiers Analog-to-digital converter (ADC) input buffers GENERAL DESCRIPTION The ADA4084-1 (single), ADA4084-2 (dual), and ADA4084-4 (quad) are single-supply, 10 MHz bandwidth amplifiers featuring rail-to-rail inputs and outputs. They are guaranteed to operate from +3 V to +30 V (or ±1.5 V to ±15 V). These amplifiers are well suited for single-supply applications requiring both ac and precision dc performance. The combination of wide bandwidth, low noise, and precision makes the ADA4084-1/ADA4084-2/ADA4084-4 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 b...
