Replacement verdict
Compatible functional replacement candidate
The AD584SH and AD584JH are functionally equivalent precision voltage references sharing the same core architecture, output configuration, and package footprint, with the SH grade offering a tightened temperature-coefficient specification over the JH grade. The SH variant can serve as a higher-stability substitute for the JH in most designs, provided the application's thermal error budget and cost targets are validated against the tighter grade.

Key electrical and mechanical differences between the two devices
| Parameter | AD584SH | AD584JH | Why it matters |
|---|---|---|---|
| Operating Temperature Range | -55°C to +125°C | 0°C to +70°C | Defines the environments where the reference can be reliably used; the SH grade supports military/industrial extremes while the JH grade is limited to commercial temperatures. |
| Temperature Coefficient (TC) | 5 ppm/°C max (selected grade) | 15 ppm/°C max (selected grade) | Lower TC means the output voltage drifts less over temperature, which is critical for precision measurement and calibration applications. |
| Initial Accuracy (Output Tolerance) | ±0.05% max (selected grade) | ±0.1% max (selected grade) | Tighter initial tolerance reduces the need for calibration and improves absolute accuracy of the reference voltage at room temperature. |
| Grade / Screening Level | Military/industrial grade (S) | Commercial grade (J) | The grade determines screening, testing, and reliability guarantees; military grades are tested to stricter standards for harsh environments. |
| Output Voltage Options | 10.000 V, 7.5 V, 5.0 V, 2.5 V (pin-selectable) | 10.000 V, 7.5 V, 5.0 V, 2.5 V (pin-selectable) | Multiple selectable outputs allow one device to serve several reference needs; identical options mean functional interchangeability in this respect. |
| Package | TO-99 (metal can), 8-pin | TO-99 (metal can), 8-pin | Same package ensures physical and footprint compatibility, allowing drop-in substitution on an existing PCB. |
| Supply Voltage Range | +4.5 V to +30 V | +4.5 V to +30 V | Wide supply range provides design flexibility; identical ranges mean the same power supply can drive either part. |
| Output Current Capability | Sinks/sources up to 10 mA | Sinks/sources up to 10 mA | Determines the load the reference can drive directly; matching capability supports equivalent circuit designs. |
| Long-Term Stability | 25 ppm/1000 hr (typical) | 25 ppm/1000 hr (typical) | Indicates how much the output may drift over time; identical stability means comparable long-term reliability in both parts. |

Frequently asked questions
What are the primary differences between the AD584SH and AD584JH?
The main difference is the specified temperature range and corresponding accuracy grade. The AD584JH is specified over the commercial temperature range of 0°C to +70°C, while the AD584SH is specified over the industrial/military temperature range of -55°C to +125°C. Both are pin-programmable precision voltage references offering 10.000 V, 7.500 V, 5.000 V, and 2.500 V outputs, but the SH grade guarantees performance over the wider temperature span.
Are the AD584SH and AD584JH pin-compatible?
Yes. Both devices are offered in the same package type (TO-99 hermetic metal can, 8-pin) and share the identical pinout, allowing them to be used interchangeably on the same PCB footprint. The difference lies in the temperature grade and the guaranteed specifications over that range, not in the physical pin configuration.
What output voltages can the AD584SH and AD584JH provide?
Both the AD584SH and AD584JH are pin-programmable to four output voltages: 10.000 V, 7.500 V, 5.000 V, and 2.500 V. The output is selected by connecting the appropriate programming pins as described in the manufacturer datasheet. The devices also provide a buffered output and are capable of sourcing and sinking current.
Can the AD584JH be used as a drop-in replacement for the AD584SH in an industrial application?
Not reliably. The AD584JH is only specified over 0°C to +70°C, so it is not guaranteed to meet its published accuracy and drift specifications outside that range. If the application requires operation below 0°C or above +70°C, the AD584SH, which is specified over -55°C to +125°C, should be used instead. Substitution should only be made after verifying the target design's temperature requirements against the datasheet.
What is the initial accuracy of the AD584SH and AD584JH?
Both the AD584SH and AD584JH are specified with an initial accuracy of ±0.1% maximum at the 10.000 V output (and correspondingly at the other programmed outputs) at +25°C, per the Analog Devices datasheet. The tighter grade distinctions in the AD584 family relate primarily to temperature coefficient and long-term stability guarantees over the specified operating range.
Do the AD584SH and AD584JH have the same temperature coefficient specification?
The temperature coefficient is guaranteed over each device's respective specified temperature range. The AD584SH guarantees its temperature coefficient over -55°C to +125°C, while the AD584JH guarantees it over 0°C to +70°C. Because the SH grade must hold performance across a much wider span, it is the appropriate choice for applications exposed to extreme temperatures; the JH grade's drift is only assured within the commercial range.
What package type do the AD584SH and AD584JH use?
Both the AD584SH and AD584JH are supplied in an 8-pin TO-99 hermetic metal can package. This package provides a sealed, robust enclosure suitable for precision reference applications. Designers should confirm the exact package suffix and ordering code with the manufacturer or an authorized distributor before finalizing a bill of materials.
Which grade should be selected for a design that must operate below 0°C?
The AD584SH should be selected. Its specified operating temperature range of -55°C to +125°C covers sub-zero operation, whereas the AD584JH is only specified from 0°C to +70°C and its accuracy and drift are not guaranteed below 0°C. Always verify the application's full temperature profile against the datasheet before choosing a grade.
