Product details
Overview
ISL60002CIH325-TK from Renesas is a precision 2.500V floating-gate analog (FGA) voltage reference with ±2.5mV initial accuracy, 20ppm/°C temperature coefficient, and ultra-low 350nA typical supply current. It operates from 2.7V to 5.5V and delivers 7mA source/sink capability, making it ideal for high-resolution ADC/DAC biasing in portable medical instruments and battery-powered data loggers.
For engineers reviewing the ISL60002CIH325-TK datasheet, ISL60002CIH325-TK pinout, ISL60002CIH325-TK application, or ISL60002CIH325-TK equivalent, this device offers verified nanopower stability for precision analog signal chains where thermal drift and quiescent current must both be minimized without trade-offs.
Technical Context
The ISL60002CIH325-TK uses Renesas' proprietary Floating Gate Analog (FGA) technology to achieve sub-millivolt initial accuracy and low thermal hysteresis (100ppm). Its architecture eliminates trimming resistors and enables stable operation across -40°C to +85°C without external compensation.
It features a 3-terminal SOT-23 configuration with VIN, VOUT, and GND pins - no enable or serial interface - and supports capacitive loads up to 500pF while maintaining <100µV/mA load regulation over its full 7mA sourcing range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500V ±2.5mV at +25°C - ensures direct compatibility with 12–16-bit SAR ADC reference inputs requiring tight DC offset control. |
| Temperature Coefficient | 20ppm/°C - limits full-range drift to ±3.125mV over -40°C to +85°C, enabling single-point calibration in industrial sensors. |
| Supply Current | 350nA typical - allows >10-year battery life in coin-cell-powered metering applications with minimal self-heating error. |
| Load Regulation | 25–100µV/mA sourcing - maintains reference integrity under dynamic ADC sampling currents without external buffering. |
| Output Noise | 30µVP-P (0.1Hz–10Hz) - avoids quantization noise floor elevation in 24-bit delta-sigma converters. |
| Line Regulation | 80–250µV/V - rejects ripple from switching regulators feeding mixed-signal PCBs without additional LDO filtering. |
| ESD Rating | 5.5kV HBM - survives handling and board-level ESD events common in handheld test equipment assembly. |
Pinout & Package
ISL60002CIH325-TK is housed in a RoHS-compliant 3-lead SOT-23 package (P3.064A), with 1.3mm × 2.9mm footprint and 1.0mm height - compatible with standard pick-and-place and reflow processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Power Supply Input | Accepts 2.7V–5.5V input; internal regulator isolates output from supply noise and dropout effects. |
| VOUT (Pin 2) | Voltage Reference Output | Stable 2.500V source/sink node; requires 0.001µF ceramic capacitor to ground for optimal noise performance. |
| GND (Pin 3) | Ground Reference | Common return for VIN and VOUT; must be connected to low-impedance analog ground plane to minimize thermal EMF errors. |
Key Features
| Feature | Design Value |
|---|---|
| FGA Technology | Enables non-volatile, laser-trim-free voltage setting with <100ppm thermal hysteresis after temperature cycling. |
| Nanopower Operation | 350nA supply current allows integration into always-on wake-up circuits without compromising battery runtime. |
| High Output Drive | ±7mA sourcing/sinking capability eliminates need for external op-amp buffers in driving multiplexed ADC inputs. |
| Low-Frequency Noise | 30µVP-P (0.1–10Hz) ensures reference stability during slow-sampling thermocouple or strain gauge measurements. |
| X-Ray Sensitivity Warning | Post-assembly x-ray inspection may permanently shift output voltage; design-in requires avoidance or post-inspection verification. |

FAQ
What is the output voltage tolerance of the ISL60002CIH325-TK at room temperature?
The ISL60002CIH325-TK has a guaranteed initial output voltage of 2.500V ±2.5mV at +25°C, corresponding to ±0.1% accuracy. This specification is confirmed across production lots and does not require user calibration. The ISL60002CIH325-TK achieves this using Renesas' Floating Gate Analog (FGA) process, eliminating laser trimming and ensuring long-term stability.
Can the ISL60002CIH325-TK drive a 10kΩ load directly without buffer amplification?
Yes - the ISL60002CIH325-TK can source or sink up to ±7mA, meaning it can drive a 10kΩ load at 2.5V with only 0.25mA current draw. Load regulation is specified at 25–100µV/mA, so the resulting error would be ≤25µV - well within its ±2.5mV initial accuracy. No buffer is required for typical ADC reference or sensor bias applications.
Is x-ray inspection safe for boards populated with ISL60002CIH325-TK?
No - post-assembly x-ray inspection can cause permanent output voltage shift in the ISL60002CIH325-TK due to FGA cell charge perturbation. Renesas explicitly advises minimizing or avoiding x-ray exposure. If inspection is unavoidable, verify post-process output voltage shift (up to 10mV possible under extreme conditions) and implement functional test screening.
What is the maximum operating temperature range for the ISL60002CIH325-TK?
The ISL60002CIH325-TK is rated for operation from -40°C to +85°C, consistent with the ISL60002-25 variant group. Its 20ppm/°C temperature coefficient and 100ppm thermal hysteresis are characterized across this full range. Note that the 3.3V variants (e.g., ISL60002CAH333Z-TK) extend to +105°C, but ISL60002CIH325-TK does not.
Does the ISL60002CIH325-TK require an external output capacitor?
Yes - a 0.001µF ceramic capacitor is required between VOUT and GND for optimal noise performance and stability, per the datasheet's "Recommended Operating Conditions." Larger values (e.g., 10µF) may be added in parallel for improved low-frequency PSRR, but the 1nF capacitor is mandatory to suppress high-frequency oscillation and ensure 30µVP-P noise spec compliance.
