INA225AIDGKR Information
Description
The INA225AIDGKR is a bidirectional, programmable gain amplifier IC from Texas Instruments. It's designed for monitoring power and current in various applications. The device features a wide common-mode range of 0V to 36V, making it suitable for use with a variety of voltage levels. The amplifier has four programmable gains: 25V/V, 50V/V, 100V/V, and 200V/V, allowing users to adjust the gain to suit their specific application. The device also offers a high bandwidth of 250 kHz (at a gain of 25V/V) and low quiescent current consumption of 350 µA. The INA225AIDGKR is available in an MSOP-8 package and is suitable for use in a range of applications, including power supplies, motor control systems, and energy monitoring systems.
Features
The INA225AIDGKR features:
- Wide common-mode range: 0 V to 36 V
- Offset voltage: ±150 µV (Max, All Gains)
- Offset voltage drift: 0.5 µV/°C (Max)
- Gain accuracy over temperature (Max): ±0.15% for 25 V/V and 50 V/V gains, ±0.2% for 100 V/V gain, and ±0.3% for 200 V/V gain
- 10-ppm/°C gain drift
- 250-kHz bandwidth (Gain = 25 V/V)
- Programmable gains: G1 = 25 V/V, G2 = 50 V/V, G3 = 100 V/V, and G4 = 200 V/V
- Quiescent current: 350 µA (Max)
These features make the INA225AIDGKR suitable for monitoring power supplies, motor control circuits, and other applications where high accuracy and stability are required.
