The maximum power dissipation of INA2133U/2K5 is 670mW at 25°C. However, it's recommended to keep the power dissipation below 500mW to ensure reliable operation.
To minimize noise and ensure accurate measurements, it's 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, use a low-impedance path for the input signals and keep the input traces as short as possible.
The recommended input impedance for INA2133U/2K5 is 1kΩ or higher. This ensures that the input signal is not attenuated and the amplifier operates within its specified gain range.
INA2133U/2K5 is designed for low-frequency applications up to 50kHz. While it may work for higher frequencies, its performance may degrade, and it's not recommended for high-frequency applications above 100kHz.
The gain of INA2133U/2K5 can be calculated using the formula: Gain = 1 + (R2/R1), where R1 and R2 are the external resistors connected to the gain pins. The gain range is from 1 to 100.
