Product details
Overview
ZXRE1004DN8TA from Diodes Incorporated is a 1.22 V bandgap voltage reference IC optimized for ultra-low-power operation at 4 µA typical knee current, ±1% initial tolerance, and 20 ppm/°C typical temperature coefficient in SOT23 package-designed for precision analog signal conditioning in battery-powered portable instrumentation and data acquisition systems.
For engineers reviewing the ZXRE1004DN8TA datasheet, ZXRE1004DN8TA pinout, ZXRE1004DN8TA application, or ZXRE1004DN8TA equivalent, key selection criteria include low-quiescent-current stability across 8 µA–20 mA load range, unconditional capacitive-load stability, and compatibility with space-constrained PCB layouts requiring SOT23 footprint.
Technical Context
The ZXRE1004DN8TA operates as a two-terminal shunt reference, sinking current to maintain a stable 1.22 V reverse breakdown voltage across its anode-cathode terminals. Its bandgap core delivers predictable output over −40°C to +85°C with minimal drift, supported by low dynamic impedance (0.2 Ω typical at 1 mA) and wideband noise of 60 µV(rms) (10 Hz–10 kHz).
It functions without external biasing components and remains unconditionally stable with capacitive loads up to several microfarads-enabling direct integration into ADC reference inputs, sensor excitation circuits, and low-power LDO feedback networks without compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reference Voltage | 1.22 V nominal; maintains ±1% accuracy over initial calibration at 25°C |
| Knee Current | 4 µA typical; minimum current required to establish regulation, enabling ultra-low-power sleep-mode referencing |
| Temp Coefficient | 20 ppm/°C typical; ensures ≤2.5 mV total drift over −40°C to +85°C operating range |
| Operating Current Range | 8 µA to 20 mA; supports wide dynamic headroom for varying load conditions without dropout |
| Dynamic Impedance | 0.2 Ω typical at 1 mA; minimizes load-induced voltage perturbation in precision feedback paths |
| Wideband Noise | 60 µV(rms), 10 Hz–10 kHz; suitable for 12-bit+ ADC reference without additional filtering |
Pinout & Package
SOT23-3 package (JEDEC TO-236AB), 2.80–3.04 mm × 2.10–2.64 mm footprint, 1.12 mm max height, with gull-wing leads for reflow-compatible surface mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current sink input | Connected to system ground or regulated node; sets reference return path |
| Cathode (Pin 2) | Output reference node | Provides stable 1.22 V relative to anode; connects to ADC REF+, sensor bridge top, or LDO feedback |
| No-connect (Pin 3) | Unused terminal | Floating per datasheet; must not be tied to any potential-no internal connection |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low knee current | 4 µA typical enables operation from microamp-level bias sources, extending battery life in always-on sensors |
| Unconditional stability | No external capacitor required for stability-even with >1 µF bypass capacitance on cathode |
| Shunt topology | Two-terminal architecture simplifies layout and eliminates need for dedicated supply rail or series resistor calculation |
| Lead-free & green compliance | Fully RoHS 3 compliant with <900 ppm Br/Cl and <1000 ppm Sb-meets industrial and medical environmental requirements |
Applications
| Battery-Powered Data Loggers | Precision Portable Multimeters |
|---|---|
Use Scenario: Continuous low-power sampling of temperature/humidity sensors over multi-day battery life. IC Role / Device Role / Timing Role: Shunt reference providing stable 1.22 V for 16-bit sigma-delta ADC conversion. Use Value: 4 µA knee current minimizes quiescent drain; 20 ppm/°C TC ensures <±3 LSB error across operating temperature range. | Use Scenario: Handheld multimeter requiring accurate DC voltage measurement down to 100 mV full-scale. IC Role / Device Role / Timing Role: Primary reference for autoranging analog front-end and digital calibration offset correction. Use Value: ±1% initial tolerance and <1 mV load regulation error enable factory-trimmed accuracy without post-assembly adjustment. |
| Medical Wearable Sensor Nodes | Industrial Loop-Powered Transmitters |
Use Scenario: ECG/PPG analog front-end in compact wearable patch with coin-cell battery. IC Role / Device Role / Timing Role: Reference for low-noise instrumentation amplifier and ADC driver stage. Use Value: 60 µV(rms) broadband noise avoids SNR degradation; SOT23 footprint saves critical board area. | Use Scenario: 4–20 mA transmitter with HART modulation, powered from 24 V loop with tight power budget. IC Role / Device Role / Timing Role: Stable reference for DAC output scaling and current-sense amplifier gain setting. Use Value: 0.2 Ω dynamic impedance prevents output shift during HART frequency bursts; 8–20 mA operating range accommodates full loop dynamics. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLVH431AIDBVR | Adjustable 1.24 V reference; requires two external resistors; 80 µA typical quiescent current | Used where programmability or tighter initial tolerance (0.5%) is needed; less suitable for sub-10 µA systems | Select when adjustable output or higher accuracy outweighs current penalty |
| LM4040CIM3-ADJ | Fixed 2.048 V or 4.096 V options; 75 µA typical IQ; 100 ppm/°C max TC | Preferred in 3.3 V/5 V systems needing higher reference voltage; wider temp drift limits use in wide-range field instruments | Choose for legacy designs using LM4040 footprint or where higher VREF improves ADC resolution |
Compared with TLVH431AIDBVR and LM4040CIM3-ADJ, the ZXRE1004DN8TA uniquely balances ultra-low 4 µA operation, 1.22 V fixed output, and 20 ppm/°C stability-making it optimal for space- and energy-constrained 1.8 V–3.3 V portable systems where simplicity and efficiency are primary.

FAQ
What is the maximum capacitive load the ZXRE1004DN8TA can drive without oscillation?
The ZXRE1004DN8TA is unconditionally stable and does not require external compensation-datasheet confirms stable operation with capacitive loads up to several microfarads. No minimum or maximum CL limit is specified because oscillation is suppressed across the full operating current range (8 µA–20 mA) and temperature range (−40°C to +85°C).
Can ZXRE1004DN8TA replace LT1004CN8-1.2 in existing designs?
Yes-ZXRE1004DN8TA is pin-compatible with LT1004CN8-1.2 in SO-8 and functionally compatible in SOT23 footprint variants. Both provide 1.2 V reference, but ZXRE1004DN8TA offers lower knee current (4 µA vs. 10 µA), tighter tempco (20 ppm/°C vs. 50 ppm/°C typ), and improved noise performance (60 µV vs. 80 µV rms).
Is ZXRE1004DN8TA qualified for automotive applications?
No-ZXRE1004DN8TA is not AEC-Q100 qualified. Diodes states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing; this part is rated for industrial temperature range (−40°C to +85°C) and intended for commercial/industrial portable equipment.
How does the "No-connect" pin (Pin 3) affect PCB layout?
Pin 3 is internally unconnected and must remain floating-neither grounded nor tied to any net. PCB layout must avoid solder mask bridging or trace routing to Pin 3. The SOT23-3 package uses Pins 1 (anode) and 2 (cathode) exclusively; Pin 3 serves only mechanical alignment and has zero electrical function.
