Replacement verdict
Compatible functional replacement candidate
The AD711JNZ and AD711JN are functionally equivalent operational amplifiers sharing the same core specifications, with the primary distinction being the package finish (RoHS-compliant lead-free versus leaded). The AD711JNZ is a suitable functional replacement candidate for the AD711JN in most applications, provided that the lead-free (Pb-free) termination finish and RoHS compliance status are acceptable for the target design and manufacturing process.

Key electrical and mechanical differences between the two devices
| Parameter | AD711JNZ | AD711JN | Why it matters |
|---|---|---|---|
| Package / Mounting Type | 8-Pin PDIP (through-hole) | 8-Pin PDIP (through-hole) | Both are through-hole PDIP parts; the "Z" suffix denotes RoHS-compliant lead finish, which affects solderability and regulatory compliance. |
| RoHS Compliance | RoHS compliant (lead-free) | Non-RoHS (contains lead) | The Z suffix indicates lead-free/RoHS construction; non-compliant parts may not be usable in regulated markets or new designs. |
| Amplifier Type | Precision BiFET operational amplifier | Precision BiFET operational amplifier | Confirms both are the same core precision JFET-input op-amp family, ensuring functional equivalence. |
| Gain Bandwidth Product | 4 MHz (typ) | 4 MHz (typ) | Determines the maximum usable frequency for small-signal amplification; identical values mean equivalent AC performance. |
| Slew Rate | 20 V/µs (typ) | 20 V/µs (typ) | Sets how fast the output can respond to large signal changes; matching slew rate preserves transient behavior. |
| Input Offset Voltage | 0.5 mV max (J grade) | 0.5 mV max (J grade) | DC accuracy metric; identical offset spec ensures the same precision in DC-coupled applications. |
| Input Bias Current | 25 pA typ (JFET input) | 25 pA typ (JFET input) | Low bias current is critical for high-impedance sensor and integrator circuits; matching values preserve input loading behavior. |
| Supply Voltage Range | ±4.5 V to ±18 V | ±4.5 V to ±18 V | Defines compatible power rails; identical range allows drop-in use in the same supply environment. |
| Operating Temperature Range | 0°C to +70°C (commercial) | 0°C to +70°C (commercial) | Ensures both parts meet the same environmental operating limits for the target application. |

Frequently asked questions
What is the difference between the AD711JNZ and the AD711JN?
The AD711JNZ and AD711JN refer to the same Analog Devices AD711 precision operational amplifier in the commercial J-grade (0°C to +70°C) in an 8-lead PDIP package. The "Z" suffix denotes RoHS-compliant lead-free packaging, while the non-Z "AD711JN" designation refers to the older lead-containing (non-RoHS) package version. Electrically, both are specified identically in the datasheet.
Are the AD711JNZ and AD711JN electrically identical?
Yes. Both parts share the same AD711 die and J-grade specifications: typical input offset voltage of 0.5 mV (1 mV max), input bias current of 25 pA typical, 16 V/µs slew rate, and 4 MHz unity-gain bandwidth. The only documented difference is the package finish (RoHS-compliant vs. non-RoHS).
Can the AD711JNZ be used as a direct replacement for the AD711JN?
Yes, in most cases. Both are 8-lead PDIP devices with identical pinouts and electrical specifications, so the AD711JNZ is a functional drop-in replacement for the AD711JN. The substitution should be validated against the target design's requirements and the manufacturer's datasheet, particularly regarding solder process compatibility for the RoHS lead-free finish.
What is the significance of the "Z" suffix on the AD711JNZ?
The "Z" suffix in Analog Devices nomenclature indicates a RoHS-compliant package. The AD711JNZ uses a lead-free (Pb-free) finish and is compliant with RoHS directives, whereas the AD711JN uses a traditional tin-lead finish and is not RoHS-compliant.
What are the key specifications of the AD711JNZ/AD711JN?
Both are precision BiFET operational amplifiers with: 4 MHz unity-gain bandwidth, 16 V/µs slew rate, 0.5 mV typical input offset voltage (1 mV max for J grade), 25 pA typical input bias current, 0.0003% typical THD, and operation on ±4.5 V to ±18 V dual supplies. They are specified over the 0°C to +70°C commercial temperature range.
Are the AD711JNZ and AD711JN available in the same package?
Yes. Both are offered in the 8-lead PDIP (N) package with identical pin assignments and mechanical dimensions. The package difference is limited to the lead finish (RoHS-compliant vs. non-RoHS).
Which part should be selected for a new RoHS-compliant design?
The AD711JNZ should be selected for new designs requiring RoHS compliance, as it carries the lead-free, RoHS-compliant package finish. The AD711JN (non-Z) is the legacy non-RoHS version and is generally not recommended for new RoHS-restricted designs.
