Key electrical and mechanical differences between the two devices
| Parameter | AD780BRZ-REEL | AD780BRZ | Why it matters |
|---|---|---|---|
| Reference Type | Series / Shunt | Series / Shunt | Both parts share the same reference architecture, so they are functionally interchangeable in circuit design. |
| Output Voltage | 2.5 V or 3.0 V (pin-selectable) | 2.5 V or 3.0 V (pin-selectable) | Identical selectable output voltages ensure the same system supply rails can be supported by either part. |
| Initial Accuracy | ±1 mV (max, B grade) | ±1 mV (max, B grade) | Matching initial accuracy guarantees equivalent precision performance in the target application. |
| Temperature Coefficient | 3 ppm/°C (max, B grade) | 3 ppm/°C (max, B grade) | Identical drift specification ensures the same stability over temperature for both parts. |
| Output Current Capability | ±10 mA | ±10 mA | Same drive capability means either part can source/sink the same load current. |
| Supply Voltage Range | 4.0 V to 36 V | 4.0 V to 36 V | Equivalent input supply range allows the same power source to be used with either device. |
| Package / Mounting | 8-SOIC, Surface Mount | 8-SOIC, Surface Mount | Same package and footprint enable drop-in replacement on the same PCB. |
| Packaging / Delivery Form | Tape & Reel | Tube / Bulk | Delivery form differs, affecting automated assembly handling versus manual or low-volume use, though the device itself is identical. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Same temperature range ensures equivalent environmental suitability for both parts. |

Frequently asked questions
What is the difference between AD780BRZ-REEL and AD780BRZ?
Both parts are the same AD780 voltage reference device in an 8-lead SOIC package with the same specified grade and temperature range. The only difference is packaging format: AD780BRZ is supplied in tube/tray form, while AD780BRZ-REEL is supplied on tape-and-reel for automated assembly. Electrical performance and specifications are identical.
Are AD780BRZ-REEL and AD780BRZ electrically interchangeable?
Yes. Since both are the same AD780BRZ die and grade in the same 8-lead SOIC package, they are electrically and functionally interchangeable. The choice between them is based on assembly method (reel vs. tube) rather than electrical characteristics.
What output voltage options does the AD780 provide?
The AD780 is a pin-programmable voltage reference offering a 2.5 V output and a 3.0 V output, selectable via the appropriate pin connection. It is specified for initial accuracy and low temperature drift, making it suitable for precision data conversion and instrumentation applications.
What package does the AD780BRZ use?
The AD780BRZ and AD780BRZ-REEL are both supplied in an 8-lead SOIC package (the "RZ" suffix denotes the SOIC package and RoHS-compliant construction). The package and pinout are identical between the two ordering codes.
Does the tape-and-reel packaging of AD780BRZ-REEL affect its technical specifications?
No. Tape-and-reel is a shipping and handling format only. The AD780BRZ-REEL contains the same device as AD780BRZ, and all datasheet electrical specifications, accuracy grades, and temperature performance apply equally to both.
Which part should be selected for high-volume automated PCB assembly?
AD780BRZ-REEL is the appropriate choice for automated pick-and-place assembly lines because it is supplied on tape-and-reel. AD780BRZ, supplied in tube form, is typically used for prototyping, low-volume runs, or manual handling.
Are both AD780BRZ-REEL and AD780BRZ RoHS compliant?
Yes. The "Z" in both ordering codes indicates RoHS-compliant construction per the manufacturer's ordering guide. Both variants share the same RoHS status and package material composition.
