AD8502ARJZ-REEL7

AD8502 is a low-power, precision CMOS operational amplifier featuring a maximum supply current of 1μA per amplifier. This has a maximum offset voltage of 3mV and a typical input bias current of 1pA operating rail to rail on both the input and output. With its low power consumption, low input bias current, and rail-to-rail input and output, this is ideally suited for a variety of battery-powered portable applications. Potential applications include bedside monitors, pulse monitors, glucose meters, smoke and fire detectors, vibration monitors, and backup battery sensors. The ability to swing rail-to-rail at both the input and output helps maximize dynamic range and signal-to-noise ratio in systems that operate at very low voltages. Application includes portable equipment, remote sensors, low power filters, threshold detectors, and current sensing.

• Typical supply current/amplifier is 0.75μA (VO=VS/2, VS=5V, VCM=VS/2, TA=25°C)
• Typical offset voltage is 0.5mV (0V <lt/> VCM <lt/> 5V, VS=5V, VCM=VS/2, TA=25°C)
• Rail-to-rail input and output, no phase reversal, unity gain stable
• Input voltage range from 0 to 5.0V (VS=5V, VCM=VS/2, TA=25°C)
• Typical common-mode rejection ratio is 76dB (0V <lt/> VCM <lt/> 5V, VS=5V, VCM=VS/2, TA=25°C)
• Typical output voltage high is 4.990V (RLOAD=100Kohm to GND, TA=25°C)
• Typical slew rate is 0.004V/μs (RLOAD=1Mohm, TA=25°C)
• Temperature rating range from -40°C to +125°C
• 8-lead SOT-23 package
