Product details
Overview
ISL60002BIH312 from Renesas is a precision floating-gate analog (FGA) voltage reference delivering 1.250V output with ±1.0mV initial accuracy, 20ppm/°C temperature coefficient, and ultra-low 350nA typical supply current in a 3-lead SOT-23 package. It operates from 2.7V to 5.5V supply and supports ±7mA output sourcing/sinking, making it ideal for high-resolution ADC/DAC biasing in portable medical sensors and battery-powered instrumentation.
For engineers reviewing the ISL60002BIH312 datasheet, ISL60002BIH312 pinout, ISL60002BIH312 application, or ISL60002BIH312 equivalent, this page delivers verified specifications, thermal stability data, load regulation performance, and real-world design considerations for low-power precision analog systems requiring sub-millivolt accuracy across -40°C to +85°C.
Technical Context
The ISL60002BIH312 uses Renesas' proprietary Floating Gate Analog (FGA) technology to achieve nanoscale trimming of reference voltage without laser adjustment, enabling ±1.0mV initial accuracy at +25°C and stable 20ppm/°C drift over industrial temperature range. Its architecture eliminates trade-offs between power consumption and thermal stability.
It features a fully buffered output stage capable of ±7mA drive, low 30µVP-P (0.1Hz–10Hz) noise, and robust 5.5kV HBM ESD protection. The device maintains specified line regulation (80–250µV/V) and load regulation (25–150µV/mA) under varying input and output conditions, supporting direct interface with 16- to 24-bit converters.

FAQ
What is the output voltage tolerance of the ISL60002BIH312 over its full operating temperature range?
The ISL60002BIH312 has a guaranteed initial accuracy of ±1.0mV at +25°C and a temperature coefficient of 20ppm/°C. Over the full -40°C to +85°C range, total output variation is typically ≤±1.56mV (1.250V × 20ppm/°C × 125°C), confirmed by box-method testing in the FN8082 datasheet. This ensures reliable performance in uncontrolled ambient environments without recalibration.
Can the ISL60002BIH312 drive a 10nF capacitive load directly without oscillation?
Yes, the ISL60002BIH312 is internally compensated and stable with capacitive loads up to at least 100nF, as validated in Figure 13 (ZOUT vs frequency) and transient response curves (Figures 6–10) of the FN8082 datasheet. Its low output impedance (<1Ω at DC, <10Ω up to 10kHz) ensures monotonic settling and no peaking, even with 10nF ceramic decoupling on VOUT.
Is x-ray inspection safe for ISL60002BIH312 during PCB assembly?
No-post-assembly x-ray inspection can cause permanent shifts in the ISL60002BIH312 output voltage due to ionizing radiation effects on its floating-gate structure. The datasheet explicitly warns against x-ray exposure (page 1, Applications Information, and page 34). If inspection is unavoidable, voltage verification post-inspection is mandatory, and alternative methods (e.g., optical AOI) are strongly preferred for ISL60002BIH312-equipped boards.
How does the ISL60002BIH312 compare to standard bandgap references in terms of long-term stability?
The ISL60002BIH312 exhibits 50ppm long-term stability over the first 1000 hours (FN8082, page 9), significantly better than typical bandgap references (often 100–200ppm). Its FGA technology provides non-volatile trimming with logarithmic drift that diminishes over time-reaching ~10ppm after 1000 hours-making it suitable for applications requiring decade-level calibration retention without field recalibration.
What is the maximum allowable supply voltage for ISL60002BIH312, and what happens if exceeded?
The absolute maximum VIN is +6.5V (FN8082, page 5). Exceeding this risks permanent damage to the internal FGA cell and output stage. At voltages above 5.5V-the recommended maximum-the device remains functional but may exhibit increased supply current, degraded line regulation, and accelerated long-term drift. Operation beyond +6.5V voids reliability guarantees and may cause immediate failure.
