Key electrical and mechanical differences between the two devices
| Parameter | AD711JNZ | AD7111KNZ | Why it matters |
|---|---|---|---|
| Manufacturer | Analog Devices | Analog Devices | Confirms both parts originate from the same vendor, simplifying sourcing and documentation. |
| Part Category | Operational Amplifier (Op-Amp) | Multiplying Digital-to-Analog Converter (DAC) | These are fundamentally different device classes, so they are not functionally substitutable in a circuit. |
| Package / Mounting | 8-Pin PDIP (through-hole) | 16-Pin PDIP (through-hole) | Different pin counts and footprints mean they cannot share the same PCB layout. |
| Supply Voltage Range | ±4.5 V to ±18 V (dual supply) | +5 V to +15 V (single supply, VDD) | Supply requirements differ, affecting power rail design and compatibility. |
| Primary Function | Precision high-speed voltage amplification | 8-bit digital-to-analog conversion with multiplication | The core signal-processing role differs, so one cannot replace the other in an application. |
| Number of Channels | 1 (single op-amp) | 1 (single DAC) | Both are single-channel devices, but channel type (analog amp vs digital input) differs. |
| Operating Temperature Range | 0 °C to +70 °C (commercial) | 0 °C to +70 °C (commercial) | Identical temperature ratings allow use in the same ambient environments. |
| Key Dynamic Specification | 16 V/µs slew rate, 4 MHz gain bandwidth | 8-bit resolution, current output settling | The headline performance metrics address entirely different signal-path functions. |

Frequently asked questions
Are the AD711JNZ and AD7111KNZ interchangeable?
No. The AD711JNZ is a precision low-noise operational amplifier, while the AD7111KNZ is a multiplying digital-to-analog converter. They are different functional device categories and cannot be substituted for one another.
What are the key functional differences between the AD711JNZ and AD7111KNZ?
The AD711JNZ is a single op amp offering high open-loop gain, low offset voltage, and low noise for precision analog signal conditioning. The AD7111KNZ is a CMOS multiplying DAC that converts digital input codes into an analog output proportional to a reference voltage, intended for digital-to-analog conversion and multiplying applications.
What package types do the AD711JNZ and AD7111KNZ use?
Both devices are supplied in through-hole packages. The AD711JNZ is offered in an 8-lead PDIP, and the AD7111KNZ is offered in a 16-lead PDIP, so their pin counts and PCB footprints differ.
Can the AD711JNZ and AD7111KNZ operate from the same supply voltages?
No. The AD711JNZ is specified for dual-supply operation (typically ±15 V), while the AD7111KNZ is a 5 V single-supply CMOS DAC. Their supply requirements and logic interface levels are not compatible.
Do the AD711JNZ and AD7111KNZ share the same pinout?
No. The AD711JNZ uses an 8-pin op amp pinout (offset null, inputs, supply, output), whereas the AD7111KNZ uses a 16-pin DAC pinout including digital data inputs, reference input, and analog output. The pin functions and pin counts are entirely different.
Which device should be selected for precision analog signal amplification?
The AD711JNZ is the appropriate choice for precision amplification, buffering, and active filtering tasks because it is a low-noise, high-gain operational amplifier. The AD7111KNZ is not an amplifier and cannot perform these functions.
Which device should be selected for digital-to-analog conversion or multiplying applications?
The AD7111KNZ is the correct choice for digital-to-analog conversion and multiplying DAC applications, as it accepts digital input codes and produces a scaled analog output. The AD711JNZ has no digital interface and cannot perform D/A conversion.
Are the AD711JNZ and AD7111KNZ RoHS compliant?
Both the AD711JNZ and AD7111KNZ are available in RoHS-compliant versions as indicated by the "Z" suffix in the ordering code, which denotes lead-free (Pb-free) packaging per Analog Devices ordering conventions. Designers should confirm the specific orderable part number against the manufacturer datasheet for the target assembly.
