Product details
Overview
ISL60002BIH325 from Renesas is a precision 2.500V floating-gate analog (FGA) voltage reference IC with ±1.0mV initial accuracy, 20ppm/°C temperature coefficient, 350nA typical supply current, and operation from 2.7V to 5.5V. It serves as a stable, ultra-low-power reference for high-resolution ADCs/DACs in portable medical instruments and battery-powered data loggers.
For engineers reviewing the ISL60002BIH325 datasheet, ISL60002BIH325 pinout, ISL60002BIH325 application, or ISL60002BIH325 equivalent, key selection criteria include its guaranteed 2.500V output tolerance at ±1.0mV over -40°C to +85°C, sub-1µV/mA load regulation, and compatibility with 0.001µF output capacitance in space-constrained designs.
Technical Context
The ISL60002BIH325 employs Renesas' proprietary Floating Gate Analog (FGA) technology to achieve nanoscale trimming of reference voltage without laser adjustment, enabling stable 2.500V output with minimal thermal drift. Its architecture supports sourcing and sinking up to ±7mA while maintaining <100µV/mA load regulation across industrial temperature range.
It features integrated ESD protection (5.5kV HBM), operates down to 2.7V supply, and delivers 30µVP-P low-frequency noise (0.1Hz–10Hz). Post-assembly x-ray exposure must be avoided due to permanent output voltage shift risk-confirmed by AN1533.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500V ±1.0mV at +25°C - enables direct interface with 2.5V-rail ADCs without gain calibration |
| Temp Coefficient | 20ppm/°C - ensures ≤312.5µV drift over -40°C to +85°C, critical for 16-bit+ systems |
| Supply Current | 350nA typ - allows >10-year battery life in always-on sensor nodes with coin-cell power |
| Load Regulation | 25–100µV/mA sourcing - maintains reference stability under dynamic DAC load switching |
| Line Regulation | 80–250µV/V - rejects ripple from noisy DC-DC converters feeding the reference input |
| Output Noise | 30µVP-P (0.1–10Hz) - avoids quantization noise floor elevation in precision measurement front-ends |
| ESD Rating | 5.5kV HBM - survives handling in uncontrolled assembly environments without external protection |
Pinout & Package
Package: 3-lead SOT-23 (RoHS-compliant, P3.064A outline), footprint-compatible with industry-standard voltage references and suitable for automated placement on high-density PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Power Supply Input | Accepts 2.7V–5.5V; requires local 0.1µF bypass capacitor to suppress supply noise coupling into reference output |
| VOUT (Pin 2) | Voltage Reference Output | Provides regulated 2.500V; drives ADC REF inputs directly; stable with 0.001µF–10µF capacitive loads |
| GND (Pin 3) | Ground Reference | Must connect to clean analog ground plane; shared GND path with load increases error via IR drop |
Key Features
| Feature | Design Value |
|---|---|
| FGA Technology Trim | Enables ±1.0mV initial accuracy without post-package trimming-reduces test cost and improves yield consistency |
| Nanopower Operation | 350nA supply current allows use in energy-harvesting systems where quiescent power dominates total consumption |
| Low Thermal Hysteresis | 100ppm after -40°C ↔ +85°C cycling-ensures repeatable calibration across field temperature excursions |
| High Output Drive | ±7mA sourcing/sinking capability eliminates need for external buffer in most 12–16-bit converter applications |
| Robust Capacitive Load Stability | Stable with 0.001µF to 10µF output capacitance-supports ceramic, tantalum, or polymer caps without phase-margin risk |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3025AIDBZR | 2.5V output, ±2mV initial accuracy, 50ppm/°C TC, 50µA supply current | Higher power and lower accuracy make it unsuitable for battery-critical or 16-bit+ resolution systems | Select when cost sensitivity outweighs ultra-low power and tight TC requirements |
| ADR3425ARJZ-R7 | 2.5V output, ±1.5mV initial accuracy, 10ppm/°C TC, 120µA supply current | Lower TC but 340× higher supply current limits use in energy harvesting or long-life battery apps | Prefer when ultra-low drift dominates over quiescent power budget |
Compared with REF3025AIDBZR and ADR3425ARJZ-R7, the ISL60002BIH325 uniquely combines ±1.0mV accuracy, 20ppm/°C TC, and 350nA supply current-making it the only option viable for 16-bit+ portable instrumentation requiring >5-year battery life and metrology-grade stability.

FAQ
What is the output voltage tolerance and temperature coefficient of the ISL60002BIH325?
The ISL60002BIH325 provides a nominal 2.500V output with ±1.0mV initial accuracy at +25°C and a guaranteed temperature coefficient of 20ppm/°C over -40°C to +85°C. This translates to a maximum output variation of ±312.5µV across the full industrial temperature range, supporting 16-bit system accuracy without software correction.
Can the ISL60002BIH325 drive an ADC reference input directly without a buffer amplifier?
Yes, the ISL60002BIH325 can directly drive most SAR and sigma-delta ADC reference inputs. It sources and sinks up to ±7mA with load regulation of 25–100µV/mA, and remains stable with output capacitances from 0.001µF to 10µF-eliminating the need for external buffering in typical 12–16-bit converter applications.
Is x-ray inspection safe for ISL60002BIH325 during PCB assembly?
No-x-ray inspection must be minimized or avoided for ISL60002BIH325. Renesas AN1533 confirms that post-assembly x-ray exposure causes permanent shifts in output voltage, potentially exceeding 10mV under extreme conditions. If inspection is unavoidable, verify output voltage post-reflow and post-x-ray to confirm no excessive drift occurred.
What is the minimum supply voltage required for proper operation of ISL60002BIH325?
The ISL60002BIH325 operates from a minimum supply voltage of 2.7V up to 5.5V. Below 2.7V, regulation degrades and output voltage drops nonlinearly; operation at 2.7V is fully specified and supported across the -40°C to +85°C temperature range, enabling use with single Li-ion or dual alkaline cells.
How does the ISL60002BIH325 compare to standard bandgap references in terms of long-term stability?
The ISL60002BIH325 exhibits 50ppm long-term stability over the first 1000 hours at +25°C-comparable to premium bandgap references-but achieves this with 350nA supply current, whereas typical bandgaps consume 10–100µA. Its FGA technology also delivers lower thermal hysteresis (100ppm) than conventional trimmed bandgaps.
