THS4221DGKR

THS4221DGKR Description

The THS4221DGKR from Texas Instruments is a high-performance voltage feedback operational amplifier (op-amp) designed for precision and high-speed applications. Packaged in an 8-VSSOP form factor with tape-and-reel (TR) mounting, this ROHS3-compliant and REACH-unaffected IC operates over a wide supply voltage range of 2.7V to 15V, making it versatile for various power configurations. With a gain bandwidth product (GBWP) of 120 MHz and a slew rate of 990V/µs, it delivers exceptional signal fidelity and transient response, ideal for demanding analog circuits. The low input bias current (900 nA) and moderate input offset voltage (3 mV) ensure accuracy in sensitive measurement systems.

THS4221DGKR Features

• High-Speed Performance: 230 MHz bandwidth and 990V/µs slew rate enable rapid signal processing.
• Wide Supply Range: 2.7V to 15V operation supports both low-power and high-voltage designs.
