Product details
Overview
ISL60002DIH311Z-TK from Renesas is a precision 1.200V floating-gate analog (FGA) voltage reference IC with ±5.0mV initial accuracy, 20ppm/°C temperature coefficient, and ultra-low 350nA typical supply current. It operates from 2.7V to 5.5V supply and delivers 7mA source/sink capability in a 3-lead SOT-23 package, designed for high-resolution data converters in portable medical and industrial instrumentation.
For engineers reviewing the ISL60002DIH311Z-TK datasheet, ISL60002DIH311Z-TK pinout, ISL60002DIH311Z-TK application, or ISL60002DIH311Z-TK equivalent, this device supports low-power, thermally stable reference design in battery-operated A/D systems where nanoscale drift and x-ray sensitivity must be managed during assembly and operation.
Technical Context
The ISL60002DIH311Z-TK uses Renesas' proprietary Floating Gate Analog (FGA) technology to achieve sub-millivolt initial accuracy without trimming resistors, enabling single-die precision across -40°C to +85°C. Its architecture integrates a bandgap-derived core with FGA charge storage for long-term stability and minimal thermal hysteresis (100ppm).
It features rail-to-rail output drive (±7mA), low 30µVP-P 0.1Hz–10Hz noise, and load regulation of 25–100µV/mA sourcing - all while maintaining 350nA quiescent current. Line regulation is specified at 80–250µV/V over its full input range, supporting stable operation in noisy or variable-supply environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.200V ±5.0mV at +25°C - enables direct interface with 12-bit+ SAR ADCs requiring precise mid-scale reference. |
| Temp. Coefficient | 20ppm/°C - ensures ≤150µV drift over -40°C to +85°C, critical for uncalibrated portable measurement systems. |
| Supply Current | 350nA typ - allows >10-year battery life in always-on sensor nodes powered by coin cells. |
| Load Drive | ±7mA - supports direct driving of ADC reference inputs and small op-amp bias networks without external buffers. |
| Noise (0.1–10Hz) | 30µVP-P - minimizes quantization uncertainty in 16-bit+ delta-sigma converters. |
| Input Range | 2.7V to 5.5V - compatible with Li-ion, 3.3V, and 5V rails, simplifying power domain selection in mixed-voltage designs. |
| ESD Rating | 5.5kV HBM - withstands handling in standard lab and production environments without additional protection circuitry. |
Pinout & Package
Package: 3-lead SOT-23 (RoHS-compliant, P3.064A outline), surface-mount, 1.3mm × 2.9mm footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Power Supply Input | Accepts 2.7–5.5V; internal regulation isolates output from supply ripple - no external decoupling required for basic operation. |
| VOUT (Pin 2) | Voltage Reference Output | Stable 1.200V source/sink node; connects directly to ADC REF+ or precision DAC reference input. |
| GND (Pin 3) | Ground Reference | Low-impedance return path; must be tied to clean analog ground plane to maintain 20ppm/°C performance. |
Key Features
| Feature | Design Value |
|---|---|
| FGA Technology | Eliminates laser trimming; achieves ±5.0mV initial accuracy and <50ppm first-1000-hour drift without post-package calibration. |
| Nanopower Operation | 350nA supply current enables energy harvesting and coin-cell applications where average current budget is <1µA. |
| Thermal Hysteresis | 100ppm after -40°C ↔ +85°C cycling - preserves calibration integrity in field-deployed equipment subject to ambient cycling. |
| X-Ray Sensitivity Warning | Output voltage may shift permanently under x-ray inspection; design requires avoidance or post-inspection verification per AN1533. |
| Low-Frequency Noise | 30µVP-P (0.1–10Hz) - reduces effective number of bits (ENOB) degradation in precision metrology front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6029AEUR+T | 1.200V, ±2mV initial accuracy, 3ppm/°C TC, 1.2µA supply current - higher precision but 3.4× higher power draw. | Preferred in lab-grade instruments where thermal stability dominates power constraints. | Select when TC <5ppm/°C is mandatory and supply current >1µA is acceptable. |
| ADR3412ARJZ-R7 | 1.200V, ±3mV initial accuracy, 10ppm/°C TC, 120µA supply current - lower noise (12µVP-P) but 340× higher IQ. | Suitable for mains-powered portable devices with active cooling and tighter noise budgets. | Choose when sub-15µVP-P noise is required and battery life is secondary to signal fidelity. |
Compared with MAX6029AEUR+T and ADR3412ARJZ-R7, the ISL60002DIH311Z-TK trades absolute TC and noise performance for ultra-low power and proven field reliability in uncooled, battery-limited deployments - making it optimal for maintenance-free edge sensors and consumer diagnostics.

FAQ
What is the operating temperature range for the ISL60002DIH311Z-TK?
The ISL60002DIH311Z-TK is rated for industrial operation from -40°C to +85°C. This range is validated across all electrical specifications including initial accuracy, temperature coefficient, and load regulation - ensuring consistent 1.200V reference performance in outdoor, factory-floor, and portable medical environments without derating.
Does the ISL60002DIH311Z-TK require external capacitors for stability?
The ISL60002DIH311Z-TK is internally compensated and operates stably with no output capacitor required. However, a 0.001µF ceramic capacitor placed close to VOUT improves high-frequency PSRR and transient response - especially when driving switched-capacitor ADC inputs or sharing ground with digital circuits.
Can the ISL60002DIH311Z-TK drive an ADC reference input directly?
Yes, the ISL60002DIH311Z-TK can drive most SAR and sigma-delta ADC reference inputs directly. Its ±7mA output capability exceeds the dynamic current demands of 16-bit ADCs (typically <1mA peak), and its 25–100µV/mA load regulation ensures <1LSB error even under full-scale switching transients.
How does x-ray inspection affect the ISL60002DIH311Z-TK?
Post-assembly x-ray inspection may cause permanent output voltage shift in the ISL60002DIH311Z-TK due to FGA charge disturbance. Renesas recommends minimizing or avoiding x-ray exposure; if required, verify post-inspection VOUT against spec (1.200V ±5.0mV) per AN1533 guidance to confirm no >10mV drift occurred.
What is the long-term stability specification for the ISL60002DIH311Z-TK?
The ISL60002DIH311Z-TK exhibits ≤50ppm long-term stability over the first 1000 hours at +25°C, with logarithmic drift diminishing thereafter. This translates to <0.6µV/month aging under continuous operation - supporting decade-long calibration intervals in sealed, low-power instrumentation.
