OPA743UA - Brand New TI Operational Amplifier
-
Description
The OPA743UA is a CMOS operational amplifier designed by UTC. It is specifically designed for battery-powered applications and operates on a 2.1V (Min.) single supply. The amplifier is characterized by its low quiescent current (20μA/amplifier), low offset voltage (125μV max), low input bias current (1pA), and high open-loop gain (115dB). Its rail-to-rail output can drive a 100kΩ load with accuracy ensured at ± 3mV. The OPA743UA also features completely independent circuitry for the lowest crosstalk and freedom from interaction. It is ideal for single-supply applications since the common-mode range extends to the negative supply.
Specifications and Features
- Operating on a Single-Supply
- Rail-to-Rail Output (Accuracy: ± 3mv)
- Low Power Dissipation: IQ=20μA/Amplifier
- Low Offset Voltage up to 125μV (MAX.)
- Power Supply Specified from 2.3V to 5.5V
- Halogen Free
Application Scenarios
In addition to being suitable for battery-powered applications, the OPA743UA can be used in a variety of other scenarios. It is an excellent choice for portable devices, high-impedance applications, photodiodes, pre-amps, precision integrators, medical instruments, and test equipment.
Comparison
Advantages- Low quiescent current, input bias current and offset voltage
- High open-loop gain
- Completely independent circuitry for lowest crosstalk and freedom from interaction
- Can be used in single-supply applications
Disadvantages- May not be suitable for applications with high power requirements since it has a low power dissipation
