Product details

The Analog Devices OP493EP is a quad general-purpose operational amplifier in a 14-pin DIP package — through-hole, 0.300" wide body. With a 35 kHz gain-bandwidth product and a 12 V/µs slew rate, this is a micropower part built for slow signals: sensor conditioning, battery monitoring, low-speed filtering, and industrial setpoint loops where the signal changes in milliseconds, not microseconds.

The 35 kHz gain-bandwidth product and 12 V/µs slew rate suit low-frequency signal conditioning. The 125 µV input offset and 20 nA bias current are typical for a general-purpose bipolar op-amp.

Package and mounting — through-hole still has a place

The OP493EP comes in a 14-lead PDIP (0.300" body, 7.62 mm pitch). Through-hole mounting allows socketing for easy replacement.

Frequently asked questions

Is the OP493EP a rail-to-rail output op amp?

Yes, the output swings rail-to-rail. That means you can use the full supply range for signal swing — useful in low-voltage single-supply designs where every millivolt of headroom counts.

What is the gain bandwidth product of OP493EP?

The gain-bandwidth product is 35 kHz. At a closed-loop gain of 10, you get about 3.5 kHz of bandwidth; at gain 100, about 350 Hz. This is a low-frequency part — fine for DC measurement and slow control loops, not for audio or fast ADC drivers.

What is the pinout of the OP493EP 14-DIP package?

The OP493EP uses the standard 14-pin DIP pinout for quad op-amps: pin 1 is output A, pin 2 is inverting input A, pin 3 is non-inverting input A, pin 4 is V+, pin 5 is non-inverting input B, pin 6 is inverting input B, pin 7 is output B, pin 8 is output C, pin 9 is inverting input C, pin 10 is non-inverting input C, pin 11 is V-, pin 12 is non-inverting input D, pin 13 is inverting input D, pin 14 is output D. The notch or dot marks pin 1.
