Product details
Overview
ISL60002CIH325Z-T7A from Renesas is a precision 2.500V floating-gate analog (FGA) voltage reference with ±2.5mV initial accuracy, 20ppm/°C temperature coefficient, 350nA typical supply current, and operation from 2.7V to 5.5V. It serves as a stable excitation source for high-resolution ADCs/DACs in portable medical instruments and battery-powered data loggers.
For engineers reviewing the ISL60002CIH325Z-T7A datasheet, ISL60002CIH325Z-T7A pinout, ISL60002CIH325Z-T7A application, or ISL60002CIH325Z-T7A equivalent, this page delivers verified specifications, SOT-23 terminal mapping, low-power design trade-offs, and validated alternatives for precision analog signal chains requiring sub-10ppm thermal drift and nanopower operation.
Technical Context
The ISL60002CIH325Z-T7A uses Renesas' proprietary Floating Gate Analog (FGA) technology to achieve ultra-stable output without trimming resistors or laser calibration. Its 20ppm/°C TC is measured over –40°C to +85°C using the box method, and its 350nA supply current enables multi-year battery life in always-on sensing nodes.
It delivers 7mA sourcing/sinking capability with 25–100µV/mA load regulation and supports capacitive loads up to 1nF while maintaining stability. The device exhibits 30µVP-P noise (0.1Hz–10Hz) and 100ppm thermal hysteresis after cycling across its full operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500V ±2.5mV at +25°C - ensures direct compatibility with 2.5V ADC reference inputs without gain calibration. |
| Temp. Coefficient | 20ppm/°C - limits drift to ±2.5mV over –40°C to +85°C, enabling 16-bit accuracy without software compensation. |
| Supply Current | 350nA typ - allows >10-year battery life in coin-cell-powered IoT sensors with 10µA average system current. |
| Input Voltage Range | 2.7V to 5.5V - supports direct connection to Li-ion, 3.3V, or 5V rails without LDO pre-regulation. |
| Load Regulation | 25µV/mA (source), 50µV/mA (sink) - maintains <1LSB error for 16-bit converters driving 1mA DAC buffers. |
| Output Noise | 30µVP-P (0.1Hz–10Hz) - contributes <0.5LSB noise to 2.5V, 16-bit systems (LSB = 38µV). |
| ESD Rating | 5.5kV HBM - survives handling and board-level ESD events without protection diodes. |
Pinout & Package
Package: 3-lead SOT-23 (RoHS-compliant, P3.064A outline), surface-mount, 1.3mm × 2.9mm footprint, 1.0mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Power supply input | Accepts 2.7V–5.5V; requires 0.1µF bypass capacitor close to pin to suppress line noise and ensure stability. |
| VOUT (Pin 2) | Reference voltage output | Provides regulated 2.500V; drives ADC REF pins, DAC references, or comparator thresholds with minimal loading error. |
| GND (Pin 3) | Analog ground return | Must connect to clean analog ground plane; shared ground with VIN degrades PSRR by >20dB. |
Key Features
| Feature | Design Value |
|---|---|
| FGA technology | Eliminates post-assembly drift from trimming resistor stress; achieves <100ppm thermal hysteresis without calibration. |
| Nanopower operation | 350nA supply current enables energy harvesting and battery-backed applications where quiescent power dominates lifetime. |
| Low-output impedance | ZOUT < 1Ω at DC and < 10Ω up to 10kHz - minimizes interaction with ADC input capacitance and sampling kickback. |
| High sink/source drive | 7mA capability supports direct buffering of SAR ADC reference inputs without external op-amps. |
| X-ray sensitivity warning | Output shifts permanently under >10mRem exposure - mandates avoidance of post-assembly X-ray inspection in medical and aerospace assemblies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3425ARJZ-R7 | 2.5V, ±2mV initial accuracy, 10ppm/°C TC, 3.5µA supply current | Higher power, lower TC - suited for mains-powered lab equipment where thermal stability outweighs battery life. | Select when <10ppm/°C TC is mandatory and supply current >3µA is acceptable. |
| MAX6025AEUR+T | 2.5V, ±3mV initial accuracy, 25ppm/°C TC, 1.5µA supply current | Moderate TC, higher current - fits cost-sensitive industrial controllers with moderate accuracy needs. | Select for legacy designs already using MAX60xx footprints and where 25ppm/°C is within system budget. |
Compared with ADR3425ARJZ-R7 and MAX6025AEUR+T, the ISL60002CIH325Z-T7A uniquely combines nanopower consumption (350nA vs. µA-range), FGA-based long-term stability, and SOT-23 compatibility-making it optimal for space-constrained, battery-critical applications where sub-10ppm thermal drift must be achieved without active thermal management.

FAQ
What is the maximum load current the ISL60002CIH325Z-T7A can source or sink?
The ISL60002CIH325Z-T7A provides ±7mA sourcing and sinking capability. This allows direct driving of ADC reference inputs, DAC buffers, or comparator thresholds without external amplification. Load regulation remains within 25µV/mA (source) and 50µV/mA (sink), ensuring <1LSB error for 16-bit systems even under full 7mA load.
Does the ISL60002CIH325Z-T7A require an external capacitor on the VOUT pin?
No external capacitor is required for stability-the ISL60002CIH325Z-T7A is internally compensated and stable with capacitive loads up to 1nF. However, a 0.001µF ceramic capacitor is recommended at VOUT for noise reduction in high-resolution ADC applications, and a 0.1µF capacitor at VIN improves line rejection.
Can the ISL60002CIH325Z-T7A be used in applications requiring operation above +85°C?
No-the ISL60002CIH325Z-T7A is rated for –40°C to +85°C only. For extended temperature operation, Renesas offers the ISL60002CAH333Z-TK (3.3V, –40°C to +105°C). Using the ISL60002CIH325Z-T7A above +85°C risks exceeding maximum junction temperature and invalidating parametric guarantees.
How does X-ray inspection affect the ISL60002CIH325Z-T7A?
Post-assembly X-ray inspection can cause permanent output voltage shift in the ISL60002CIH325Z-T7A due to FGA charge trapping. Shifts of 10mV or more occur under extreme exposure (>10mRem). Renesas explicitly advises minimizing or avoiding X-ray inspection; if unavoidable, verify post-inspection output voltage to confirm no excessive drift occurred.
What is the typical turn-on time for the ISL60002CIH325Z-T7A?
The ISL60002CIH325Z-T7A achieves 90% of final output voltage in approximately 2ms when powered from 3.0V (Figure 11). Turn-on time increases slightly at lower input voltages and is unaffected by temperature across –40°C to +85°C, making it suitable for wake-up-from-sleep applications in low-power systems.
