OPA244NA/3K Information
Description
The OPA244NA/3K is a low-power, precision operational amplifier from Texas Instruments (TI). It features rail-to-rail output, making it suitable for applications where the output voltage needs to be as close as possible to the supply rails. This op-amp has a fast settling time of 100µs max and low noise of 10µVP-P (1Hz). It is designed for precision instrumentation applications, such as data acquisition systems, portable medical equipment, signal conditioning circuits, and temperature measurement systems. The OPA244NA/3K offers high stability, low power consumption, and a wide operating temperature range of -40°C to 125°C. Its key features include high common-mode rejection ratio (CMRR), high power supply rejection ratio (PSRR), and low distortion. This op-amp is suitable for applications where precision, low noise, and low power consumption are required.
