INA155EA/2K5 Frequently Asked Questions (FAQ)
-
The maximum power dissipation of INA155EA/2K5 is 670mW, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (RθJA) of 125°C/W.
-
To minimize noise and ensure accurate measurements, it is recommended to follow proper PCB layout techniques, such as separating analog and digital grounds, using a solid ground plane, and keeping sensitive analog signals away from noisy digital signals. Additionally, the INA155EA/2K5 should be placed close to the signal source and the input pins should be connected to the signal source with short, low-impedance traces.
-
The recommended input impedance for INA155EA/2K5 is 1kΩ to 10kΩ. This range provides a good balance between noise rejection and signal attenuation. However, the input impedance can be adjusted based on the specific application requirements.
-
INA155EA/2K5 is designed for low-frequency applications up to 50kHz. While it can be used for higher frequency applications, its performance may degrade due to the internal noise and bandwidth limitations. For high-frequency applications, it is recommended to use a more suitable amplifier, such as the INA155EA/1K5 or INA155EA/500.
-
The gain error of INA155EA/2K5 can be calculated using the formula: Gain Error (%) = (Vout - (Vin x Gain)) / (Vin x Gain) x 100%. Where Vin is the input voltage, Gain is the specified gain of the amplifier (e.g. 2.5V/V for INA155EA/2K5), and Vout is the output voltage.
