Description
OPA4140AIDR
Low Power, Single-Supply, Rail-to-Rail Output Operational Amplifier
Product Description
The OPA4140AIDR is a low-power, single-supply, rail-to-rail output operational amplifier designed for general-purpose applications. This device operates on a single supply voltage as low as 2.7V and features a low quiescent current of 950uA, making it suitable for battery-powered devices.
Key Features
- Low Power Consumption: 950uA quiescent current per amplifier
- Single Supply Operation: Can operate on a single supply voltage as low as 2.7V
- Rail-to-Rail Output: Output voltage swings to within millivolts of the supply rails
- High Input Impedance: Input bias current of 1pA and input offset current of 0.5pA
- Low Input Offset Voltage: 0.5mV maximum input offset voltage
- Unity-Gain Stable: Internally compensated for unity-gain stability
- Small Package Options: Available in MSOP-8, SOIC-8, and DFN-8 packages
