OPA2277UA - Brand New TI Precision OpAmps
-
Brief Description
The OPA2277UA is a CMOS operational amplifier designed and manufactured by Texas Instruments, which is ideal for battery-powered applications. It can be operated on a 2.1V (minimum) single supply and has a rail-to-rail output that can drive up to a 100kΩ load. The accuracy of the output voltage is ensured at ±3mV, and the operational amplifier is characterized by a low quiescent current, low offset voltage, low input bias current, and high open-loop gain. It features completely independent circuitry for lowest crosstalk and freedom from interaction. The OPA2277UA is suitable for portable devices, high-impedance applications, photodiode, pre-amps, precision integrators, medical instruments, and test equipment.
Specifications and Features
- Operating on a Single-Supply with a power supply specified from 2.3V to 5.5V
- Rail-to-Rail Output (Accuracy: ± 3mV)
- Low Power Dissipation: IQ=20μA/Amplifier
- Low Offset Voltage up to 125μV (MAX.)
- Halogen Free
Application Scenarios Or Other
The OPA2277UA is particularly designed for battery-powered applications due to its low power dissipation. Its common-mode range extending to the negative supply also makes it ideal for single-supply applications. In addition, it is suitable for portable devices, high-impedance applications, photodiode, pre-amps, precision integrators, medical instruments, and test equipment. Its characteristics of low quiescent current, low offset voltage, low input bias current, and high open-loop gain make it suitable for a wide range of applications.
