OP295GP

OP295GP Description

The OP295GP from Analog Devices Inc. is a dual general-purpose operational amplifier designed for precision analog applications. Housed in an 8-pin DIP through-hole package, this IC operates over a wide supply voltage range of 3V to 36V, making it versatile for both low-voltage and industrial-level designs. With a low input bias current of 7 nA and a moderate input offset voltage of 300 µV, it ensures stable performance in sensitive circuits. The 75 kHz gain bandwidth product and 0.03V/µs slew rate make it suitable for low-frequency signal conditioning. Although marked as obsolete, its robust design and 25 mA output current per channel still make it relevant for legacy systems and specific use cases.
