OPA2170AID

OPA2170AID Description

The OPA2170AID from Texas Instruments is a high-performance, general-purpose operational amplifier (op-amp) designed for precision analog applications. Housed in an 8-SOIC package, this dual-channel op-amp operates over a wide supply voltage range of 2.7V to 36V, making it versatile for both low-voltage and industrial applications. With a 1.2 MHz gain bandwidth product (GBW) and a 0.4V/µs slew rate, it delivers stable performance for signal conditioning, filtering, and amplification tasks. The device features ultra-low input bias current (8 pA) and input offset voltage (250 µV), ensuring accuracy in high-impedance and precision circuits. Its ROHS3 compliance and REACH unaffected status make it suitable for environmentally conscious designs.
