Product details
Overview
ISL60002DIH312-TK from Renesas is a precision 1.25V floating-gate analog (FGA) voltage reference with ±5.0mV initial accuracy, 20ppm/°C temperature coefficient, and ultra-low 350nA supply current. It operates from 2.7V to 5.5V and delivers 7mA source/sink capability in a 3-lead SOT-23 package, serving as a stable reference for high-resolution ADCs and portable medical instrumentation.
For engineers reviewing the ISL60002DIH312-TK datasheet, ISL60002DIH312-TK pinout, ISL60002DIH312-TK application, or ISL60002DIH312-TK equivalent, this device is selected for low-power, thermally stable analog signal chains where sub-10ppm/°C drift and nanopower operation are critical-especially in battery-powered data acquisition and precision sensor interfaces.
Technical Context
The ISL60002DIH312-TK uses Renesas' proprietary Floating Gate Analog (FGA) technology to achieve exceptional long-term stability and minimal thermal hysteresis (100ppm over +125°C cycling). Its architecture eliminates trimming resistors, enabling factory-set 1.25V output with guaranteed ±5.0mV accuracy at +25°C and monotonic temperature behavior across –40°C to +85°C.
It features a low-noise 30µVP-P (0.1Hz–10Hz) output and supports capacitive loads up to 1nF without instability. Load regulation is specified at 25–100µV/mA for sourcing and 50–150µV/mA for sinking, confirming robust performance under dynamic load conditions typical in SAR ADC reference buffers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.250V - precisely trimmed, fixed reference ideal for 12-bit+ ADCs with 2.5V full-scale input ranges. |
| Initial Accuracy | ±5.0mV at +25°C - enables direct use in systems requiring <0.4% absolute reference error without calibration. |
| Temp Coefficient | 20ppm/°C - contributes ≤156µV drift over –40°C to +85°C, supporting 16-bit resolution in industrial environments. |
| Supply Current | 350nA typ - allows multi-year operation from coin cells in portable metering and IoT edge sensors. |
| Load Drive | ±7mA - sufficient to drive ADC reference inputs and small op-amp buffers without external gain stages. |
| Output Noise | 30µVP-P (0.1–10Hz) - minimizes quantization noise floor degradation in high-dynamic-range data converters. |
| Line Regulation | 80–250µV/V - ensures stable output despite battery voltage sag or LDO dropout in portable systems. |
Pinout & Package
Package: 3-lead SOT-23 (RoHS-compliant, P3.064A outline), surface-mount, 1.3mm × 2.9mm footprint, suitable for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Power Supply Input | Accepts 2.7V–5.5V; internal regulator rejects supply ripple-critical when powered from noisy DC-DC converters. |
| VOUT (Pin 2) | Voltage Reference Output | Low-impedance 1.25V source/sink node; requires 0.001µF ceramic bypass to GND per datasheet for optimal noise and transient response. |
| GND (Pin 3) | Ground Reference | Single-point return for reference and load currents; must be connected directly to clean analog ground plane to avoid ground bounce errors. |
Key Features
| Feature | Design Value |
|---|---|
| FGA Technology | Eliminates laser trimming and resistor networks-ensures intrinsic long-term stability (<50ppm drift in first 1000 hours) and radiation-hardened output. |
| Nanopower Operation | 350nA quiescent current enables >10-year battery life in always-on environmental monitors using CR2032 cells. |
| Thermal Hysteresis | 100ppm after –40°C ↔ +85°C cycling-prevents calibration drift during field temperature excursions in automotive cabin sensors. |
| ESD Robustness | 5.5kV HBM rating-survives handling and board assembly without protection diodes, reducing BOM count in handheld test equipment. |
| Capacitive Load Stability | Stable with 0–1nF output capacitance-allows direct connection to ADC reference pins without isolation resistors or ferrites. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3412ARJZ-R7 | 1.2V output, ±1.2mV initial accuracy, 30ppm/°C TC, 330nA supply current, SOT-23-5 | Lower output voltage limits use with 2.4V ADCs; 5-pin package requires PCB redesign | Select if tighter initial accuracy (±1.2mV vs ±5.0mV) is prioritized over output voltage match and pin compatibility. |
| REF3012AIDBZR | 1.2V output, ±1.5mV initial accuracy, 50ppm/°C TC, 50µA supply current, SOT-23-3 | Higher power consumption precludes multi-year battery operation; higher TC increases drift in wide-temp environments | Choose only for cost-sensitive, non-battery applications where 50ppm/°C drift is acceptable and layout reuse is required. |

FAQ
What is the output voltage and initial accuracy of the ISL60002DIH312-TK?
The ISL60002DIH312-TK provides a precise 1.250V output voltage with ±5.0mV initial accuracy at +25°C. This specification is guaranteed across all units and enables direct integration into 12-bit to 16-bit data converter systems without system-level calibration, supporting applications like portable instrumentation and precision sensor interfaces where absolute voltage accuracy is critical.
Does the ISL60002DIH312-TK require external capacitors for stability?
Yes, the ISL60002DIH312-TK requires a 0.001µF ceramic capacitor between VOUT and GND, placed as close as possible to the device pins. This capacitor is essential for minimizing output noise, ensuring proper transient response, and maintaining stability under varying load conditions. The datasheet explicitly specifies this value and placement for optimal performance in all operating conditions.
Can the ISL60002DIH312-TK drive an ADC reference input directly?
Yes, the ISL60002DIH312-TK can drive most SAR and sigma-delta ADC reference inputs directly. With ±7mA output current capability and low output impedance, it meets the dynamic current demands of typical 12–24-bit ADCs. However, designers must verify the ADC's reference input capacitance and switching current profile against the ISL60002DIH312-TK's load regulation (25–100µV/mA sourcing) to ensure total error remains within system specifications.
What is the operating temperature range for the ISL60002DIH312-TK?
The ISL60002DIH312-TK is rated for industrial operation from –40°C to +85°C. Its 20ppm/°C temperature coefficient and 100ppm thermal hysteresis ensure predictable, repeatable performance across this full range-making it suitable for deployment in outdoor environmental sensors, industrial control modules, and automotive cabin electronics where ambient temperatures vary widely.
Is X-ray inspection safe for the ISL60002DIH312-TK during PCB assembly?
No-X-ray inspection is not recommended for the ISL60002DIH312-TK. As a Floating Gate Analog device, it is susceptible to permanent output voltage shifts (up to 10mV or more) under X-ray exposure. The datasheet explicitly advises minimizing or avoiding post-assembly X-ray inspection. If inspection is unavoidable, output voltage must be verified post-inspection to confirm no excessive drift has occurred.
