Precision Amplifiers (VOS < 1 mV, Bandwidth < 50 MHz)
Low Power (IS/Amp ≤ 1 mA) Amplifiers
AD8500: Micorpower, Precision CMOS Operational Amplifier
The AD8500 is a low power, precision CMOS op amp featuring a maximum supply current of 1 mA. The AD8500 has a maximum offset voltage of 1 mV
and a typical input bias current of 1 pA, and it operates rail-to-rail on both the input and output. The AD8500 can operate from a single-supply voltage of
+1.8 V to +5.5 V or a dual-supply voltage of 60.9 V to 62.75 V.
Features
• Supply current: 1 mA maximum
• Offset voltage: 1 mV maximum
• Single-supply or dual-supply operation
• Rail-to-rail input and output
• No phase reversal
• Unity-gain stable
Applications
• Portable equipment
• Remote sensors
• Low power filters
• Threshold detectors
