Product details
Overview
AD584JH from Analog Devices is a pin-programmable monolithic precision voltage reference IC delivering selectable 2.5 V, 5.0 V, 7.5 V, or 10.0 V outputs with ±7.5 mV initial tolerance (2.5 V), 15 ppm/°C max tempco (0°C to 70°C), and 10 mA output current capability. It serves as a stable, laser-trimmed reference for high-resolution DACs and ADCs in test equipment and industrial control systems.
For engineers reviewing the AD584JH datasheet, AD584JH pinout, AD584JH application, or AD584JH equivalent, this page delivers verified specifications, TO-99 package details, strobe-enabled power gating, 2-terminal negative reference operation, and real-world design guidance for precision analog signal chains.
Technical Context
The AD584JH integrates a laser-trimmed bandgap reference (1.215 V), programmable resistor ladder, and low-drift output buffer amplifier in a single die. Its pin-selectable outputs are achieved by hardwiring specific programming pins (Pins 2, 3, 1) without external components.
It features a dedicated STROBE terminal (Pin 5) that forces output to zero with <200 mV input, reducing quiescent current to ~100 µA in off-state. The device supports 2-terminal Zener-mode operation for −5 V/−7.5 V/−10 V negative references when COMMON is used as output.

Pinout & Package
AD584JH is housed in an 8-pin hermetically sealed TO-99 metal can (package option H-08), with tab connected to Pin 4 (COMMON). This package provides superior thermal stability and EMI immunity for precision analog applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (10.0V) | Programmable Output Tap | Primary buffered output node; connects to load or feedback network; voltage set by pin strapping |
| Pin 2 (5.0V) | Internal 5 V Tap | Used for 5 V output selection (tie to Pin 1) or as feedback point in custom voltage configurations |
| Pin 3 (2.5V) | Internal 2.5 V Tap | Used for 2.5 V output selection (tie to Pin 1) or as bias point; limited ±100 mV trim range |
| Pin 4 (COMMON) | Reference Ground / Negative Terminal | System ground reference; also output terminal in 2-terminal Zener mode for negative references |
| Pin 5 (STROBE) | Active-Low Output Disable | Pulling ≤200 mV disables output and reduces supply current to ~100 µA; TTL-compatible input |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF02CP | Fixed 5.0 V output; no pin-programmability; 25 ppm/°C max tempco (0°C–70°C); TO-99 package | Only suitable where 5 V is sufficient; lacks AD584JH's multi-voltage flexibility and strobe control | Select REF02CP only if fixed 5 V suffices and cost is prioritized over configurability and low-noise performance. |
| ADR435BRZ | Fixed 5.0 V output; 3 ppm/°C max tempco; SOIC-8; higher initial accuracy (±0.04%); no strobe or Zener-mode capability | Superior stability for metrology-grade designs but incompatible with AD584JH's pin-strapping and power-gating use cases | Choose ADR435BRZ when ultra-low tempco is critical and system architecture doesn't require programmable outputs or strobe shutdown. |
Compared with REF02CP and ADR435BRZ, the AD584JH uniquely combines pin-selectable outputs, strobe-enabled power gating, and 2-terminal negative reference operation in a single TO-99 package-making it irreplaceable in multi-voltage, low-power, or bipolar-reference systems where flexibility and integration are design priorities.

FAQ
What output voltages does the AD584JH support, and how are they selected?
The AD584JH supports four nominal output voltages: 2.5 V, 5.0 V, 7.5 V, and 10.0 V. Selection is accomplished by pin strapping-connecting specific programming pins (e.g., tie Pin 3 to Pin 1 for 2.5 V; tie Pin 2 to Pin 1 for 5.0 V) with no external components required. These configurations are defined in the AD584JH datasheet Table 4 and Figure 3, and all operate within the device's specified 4.5 V to 30 V input range.
Does the AD584JH support negative reference generation, and if so, how?
Yes, the AD584JH supports precision negative reference generation via 2-terminal Zener-mode operation. To implement −5.0 V, −7.5 V, or −10.0 V, connect V+ (Pin 8) and VOUT (Pin 1) together to system ground, route the COMMON pin (Pin 4) through a current-limiting resistor to the negative supply rail, and take the output from Pin 4. This configuration maintains the AD584JH's specified tempco and long-term stability, with typical output impedance rising from 0.2 Ω to 2 Ω.
What is the purpose and behavior of the STROBE pin (Pin 5) on the AD584JH?
The STROBE pin (Pin 5) on the AD584JH is an active-low output disable control. When pulled to ≤200 mV (e.g., via NPN transistor or open-collector gate), it forces the output to zero and reduces quiescent current to approximately 100 µA. In the enabled state (open or >2 V), the AD584JH operates normally with ~750 µA total supply current. This feature enables precise power gating in battery-operated or energy-conscious systems without external switches.
Can the AD584JH drive a 10-bit DAC reference input directly, and what are the key electrical limits?
Yes, the AD584JH can directly drive 10-bit DAC reference inputs such as those on the AD7533. Its ±10 mA output current capability, 0.2 Ω typical output impedance, and ≤50 µV p-p low-frequency noise ensure minimal code-dependent errors. Key limits include maintaining VIN ≥ VOUT + 2.5 V (e.g., ≥12.5 V for 10 V output) and limiting load current to ≤5 mA over temperature to preserve 20 ppm/mA load regulation performance.
How does the AD584JH's temperature coefficient compare across output voltages and grades?
The AD584JH guarantees ≤15 ppm/°C maximum temperature coefficient for all four output voltages (2.5 V, 5.0 V, 7.5 V, 10.0 V) over its 0°C to 70°C operating range. Differential tempco between outputs is ≤5 ppm/°C, ensuring stable voltage ratios critical for ratiometric systems. This spec is validated per AD584 Rev. C datasheet Table 1 and applies identically across all pin-programmed configurations of the AD584JH.
