THS4281DBVRG4

THS4281DBVRG4 Description

The THS4281DBVRG4 from Texas Instruments is a high-performance, voltage-feedback operational amplifier (op-amp) designed for precision analog applications. Packaged in a compact SOT23-5 surface-mount form factor, this single-channel op-amp operates over a wide supply voltage range of 2.7V to 16.5V, making it versatile for both low-voltage and industrial-level designs. With a -3dB bandwidth of 95 MHz and a slew rate of 35V/µs, it delivers excellent signal fidelity and transient response, suitable for high-speed signal conditioning. The device features a low input bias current (500 nA) and moderate input offset voltage (500 µV), ensuring accuracy in sensitive circuits. Despite its obsolete status, it remains a reliable choice for legacy designs due to its ROHS3 compliance and REACH unaffected status.
