OPA354AIDDA

OPA354AIDDA Description

The OPA354AIDDA from Texas Instruments is a high-performance, voltage-feedback operational amplifier (op-amp) designed for precision applications requiring wide bandwidth and low power consumption. Packaged in an 8-SOP with Exposed Pad, this single-channel op-amp operates over a 2.5V to 5.5V supply range, making it suitable for both portable and industrial systems. With a 100 MHz gain bandwidth product (GBW) and 150V/µs slew rate, it delivers exceptional signal fidelity for high-speed analog circuits. Its ultra-low 3 pA input bias current and 2 mV input offset voltage ensure accuracy in sensitive measurement applications.
