Quad low-power op-amp in 14-pin DIP
The OP400HPZ is a quad-channel general-purpose operational amplifier from Analog Devices in a 14-lead PDIP package (0.300-inch width). It integrates four independent amplifiers in one through-hole package, saving board space compared to four separate single op-amps while keeping the layout on a standard DIP footprint.
Parametric fit for signal-conditioning chains
Each of the four channels draws 600 µA from the supply, so the total quiescent current for the package is 2.4 mA — low enough for multi-channel battery-powered or loop-powered transmitter designs where every milliamp counts. The 500 kHz gain-bandwidth product and 0.15 V/µs slew rate set the useful signal bandwidth. For a closed-loop gain of 10, the -3 dB bandwidth is about 50 kHz, and the full-power bandwidth into a 5 V peak-to-peak output swing is roughly 4.8 kHz. This suits slow sensor conditioning, active filters below 10 kHz, and DC amplification — not video or fast ADC drivers. These figures mean the OP400HPZ resolves microvolt-level signals without external nulling in most thermocouple, strain-gauge, and bridge amplifier circuits, provided the source impedance stays below a few hundred kilohms. The supply range spans 6 V to 36 V total (dual supplies from ±3 V to ±18 V). This wide compliance lets the same part run off a single 12 V or 24 V industrial rail or split supplies without a separate regulator.
Industrial temperature and through-hole packaging
The 14-pin DIP package (0.300-inch body width) is through-hole mounted, making it breadboard-friendly for prototyping and easy to hand-solder. It also simplifies rework and socketing in legacy designs where surface-mount conversion is not an option. Supplied in tubes, the parts are aligned and protected for manual or machine insertion without the handling issues of loose or tape-packaged through-hole devices.
Production status and compliance
Because it is an active, catalog-listed device, the OP400HPZ is sourced through authorized distribution channels.
