Product details
Overview
ISL60002DIH312Z-T7A from Renesas is a precision 1.250V floating-gate analog (FGA) voltage reference with ±5.0mV initial accuracy, 20ppm/°C temperature coefficient, and ultra-low 350nA supply current in a 3-lead SOT-23 package. It operates from 2.7V to 5.5V supply and delivers 7mA source/sink capability, making it ideal for high-resolution ADC/DAC biasing in portable medical sensors and battery-powered instrumentation.
For engineers reviewing the ISL60002DIH312Z-T7A datasheet, ISL60002DIH312Z-T7A pinout, ISL60002DIH312Z-T7A application, or ISL60002DIH312Z-T7A equivalent, this page provides verified technical context, real-world design meaning of specifications, validated pin functions, and confirmed alternative options for low-power precision reference selection.
Technical Context
The ISL60002DIH312Z-T7A uses Renesas' proprietary Floating Gate Analog (FGA) technology to achieve stable 1.250V output without trimming resistors or laser calibration. Its architecture enables nanoscale charge retention on the floating gate, delivering long-term stability of 50ppm over first 1000 hours and thermal hysteresis of only 100ppm after cycling from –40°C to +85°C.
It features rail-to-rail load regulation performance (25–100µV/mA sourcing, 50–150µV/mA sinking), low 30µVP-P noise (0.1Hz–10Hz), and robust 5.5kV HBM ESD protection. The device requires no external components for basic operation but benefits from a 0.001µF output capacitor for optimal noise and transient response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.250V ±5.0mV at +25°C - sets exact full-scale reference for 12-bit+ SAR ADCs without software calibration. |
| Temp Coefficient | 20ppm/°C - contributes ≤156µV drift over –40°C to +85°C, enabling <1 LSB error in 16-bit systems. |
| Supply Current | 350nA typical - allows >10-year battery life in coin-cell-powered data loggers drawing <1µA average. |
| Load Drive | ±7mA - directly drives ADC REF pins and small op-amp buffers without external gain stages. |
| Line Regulation | 80–250µV/V - maintains <0.01% output change across full 2.7V–5.5V input range, critical for unregulated battery rails. |
| Output Noise | 30µVP-P (0.1Hz–10Hz) - avoids noise-induced quantization errors in high-resolution delta-sigma converters. |
| ESD Rating | 5.5kV HBM - survives handling and board-level ESD events without parameter shift or failure. |
Pinout & Package
Package: 3-lead SOT-23 (RoHS-compliant, P3.064A outline), footprint-compatible with industry-standard voltage references and 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 ensures stable core bias even with noisy or drooping supplies. |
| VOUT (Pin 2) | Voltage Reference Output | Delivers precise 1.250V; requires 0.001µF ceramic capacitor to GND for optimal PSRR and settling time. |
| GND (Pin 3) | Ground Reference | Must connect to clean analog ground plane; shared digital ground increases noise coupling and degrades accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| FGA Technology | Eliminates need for post-package trimming, ensuring ±5.0mV accuracy without factory calibration overhead. |
| Nanopower Operation | 350nA supply current enables use in always-on sensor nodes where µA-level leakage dominates system budget. |
| Low Thermal Hysteresis | 100ppm max after –40°C/+85°C cycling - preserves calibration integrity in field-deployed equipment undergoing ambient swings. |
| High Load Capability | ±7mA drive supports direct connection to ADC reference inputs and low-power op-amps without buffer stages. |
| Robust ESD Protection | 5.5kV HBM rating allows safe manual handling and eliminates need for external TVS on reference lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6025AEUR+T | 1.25V output, ±2mV initial accuracy, 3ppm/°C tempco, 65µA supply current, SOT-23-3 | Higher accuracy and lower tempco but 185× higher supply current limits battery life | Select when absolute precision outweighs power constraints; not suitable for >1-year battery operation |
| ADR3412ARJZ-R7 | 1.2V output, ±3mV initial accuracy, 10ppm/°C tempco, 120µA supply current, SOT-23-3 | Different nominal voltage (1.2V vs 1.25V); requires circuit redesign for ADC full-scale mapping | Choose only if system already uses 1.2V reference architecture and can tolerate 4% full-scale scaling change |
Compared with MAX6025AEUR+T and ADR3412ARJZ-R7, the ISL60002DIH312Z-T7A trades minor initial accuracy (±5mV vs ±2–3mV) for orders-of-magnitude lower power (350nA vs 65–120µA), enabling true nanopower system architectures without sacrificing 16-bit ADC performance.

FAQ
What is the output voltage tolerance and temperature coefficient of the ISL60002DIH312Z-T7A?
The ISL60002DIH312Z-T7A has a nominal output voltage of 1.250V with an initial accuracy of ±5.0mV at +25°C and a guaranteed temperature coefficient of 20ppm/°C across –40°C to +85°C. This means its output drift is bounded to ±156µV over the full industrial temperature range, supporting 16-bit ADC applications without recalibration.
Can the ISL60002DIH312Z-T7A operate from a single-cell Li-ion battery?
Yes, the ISL60002DIH312Z-T7A supports input voltages from 2.7V to 5.5V, covering the full discharge curve of a single-cell Li-ion battery (4.2V down to ~2.8V). Its 350nA supply current ensures minimal impact on battery runtime, and its 2.7V minimum VIN guarantees functionality even at end-of-discharge voltage.
Does the ISL60002DIH312Z-T7A require an external output capacitor?
Yes, the ISL60002DIH312Z-T7A requires a 0.001µF ceramic capacitor from VOUT to GND for stable operation and optimal noise performance. This capacitor reduces output impedance at high frequencies, improves PSRR, and ensures monotonic turn-on behavior. Larger capacitors (>10nF) may cause instability or slow settling.
How does X-ray inspection affect the ISL60002DIH312Z-T7A?
X-ray inspection can permanently shift the output voltage of the ISL60002DIH312Z-T7A due to ionizing radiation effects on its floating-gate structure. Shifts exceeding 10mV have been observed under extreme exposure. Renesas recommends minimizing or avoiding post-assembly X-ray inspection; if required, verify output voltage post-inspection to confirm no excessive drift occurred.
What is the maximum load current the ISL60002DIH312Z-T7A can source or sink?
The ISL60002DIH312Z-T7A can source or sink up to ±7mA while maintaining specified accuracy and regulation. This capability allows direct driving of ADC reference inputs, small op-amp buffers, or level-shifting circuits without external amplification-reducing bill-of-materials and layout complexity in precision analog designs.
