Product details

Overview

X60003CIG3Z-41 from Intersil is a precision 4.096V floating-gate analog (FGA™) voltage reference in 3-lead SOT-23 package, delivering ±2.5mV initial accuracy, 20ppm/°C temperature coefficient, and ultra-low 500nA supply current for high-resolution data acquisition systems operating from 4.5V to 9.0V input.

For engineers reviewing the X60003CIG3Z-41 datasheet, X60003CIG3Z-41 pinout, X60003CIG3Z-41 application, or X60003CIG3Z-41 equivalent, key selection criteria include nanoscale power budgeting in battery-powered ADCs, thermal hysteresis ≤150ppm, long-term stability of 50ppm over time, and compatibility with 0.001µF output capacitance for noise reduction.

Technical Context

The X60003CIG3Z-41 uses proprietary Floating Gate Analog technology to generate a stable 4.096V reference without bandgap or buried zener structures, enabling sub-1µV/mA load regulation and 100mV dropout at no load. Its CMOS-based buffer supports ±10mA sourcing/sinking while maintaining low noise (30µV_P-P, 0.1Hz–10Hz).

Designed for industrial-grade operation from –40°C to +85°C, it features 5kV HBM ESD protection, 150µV/V line regulation, and thermal hysteresis of 150ppm - all achieved with no external components beyond minimal decoupling capacitors (0.001µF typical).

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	4.096V ±2.5mV at +25°C - enables direct interface with 12–24-bit ADCs using standard 4.096V full-scale coding.
Supply Current	500nA typical - allows continuous biasing in coin-cell-powered systems for zero wake-up delay and minimized long-term drift.
Tempco	20ppm/°C - ensures ≤1.024mV total drift across –40°C to +85°C, critical for calibration-grade portable instruments.
Input Range	4.5V to 9.0V - supports single-supply operation from Li-ion batteries (3.7V nominal with boost) or industrial 5V/6V rails.
Noise (0.1–10Hz)	30µV_P-P - meets requirements for 16-bit+ precision measurement without additional filtering circuitry.
Load Regulation	10–50µV/mA sourcing - maintains <0.001% gain error in precision current sources up to 10mA output.
Long-Term Stability	50ppm (1000h) - guarantees <0.205mV output shift after one year, essential for unattended sensor nodes and metrology tools.

Pinout & Package

Package: 3-lead SOT-23 (RoHS-compliant, JEDEC TO-236, P3.064 outline), 2.37mm × 2.92mm × 0.95mm, thermal resistance θ_JA = 275°C/W.

Pin/Terminal	Circuit Role	Design Meaning
1 (VIN)	Power Supply Input	Accepts 4.5V–9.0V DC; internal regulator rejects ripple up to 150µV/V - eliminates need for LDO pre-regulation in noisy environments.
2 (VOUT)	Voltage Reference Output	Provides buffered 4.096V with 10mA sink/source capability; requires ≥0.001µF ceramic capacitor for stability and noise control.
3 (GND)	Analog Ground Reference	Must be connected to clean, low-impedance analog ground plane; separation from digital ground prevents <10µV coupling into reference path.

Key Features

Feature	Design Value
FGA™ Technology	Eliminates traditional bandgap/zener limitations - enables programmable reference voltages and near-zero supply current without sacrificing accuracy.
Nanoscale Power Consumption	500nA supply current allows permanent enable in battery-operated systems, removing turn-on settling delay (7ms typical) from measurement timing.
Low Thermal Hysteresis	150ppm after –40°C ↔ +85°C cycling - preserves calibration integrity in field-deployed equipment subjected to ambient temperature swings.
High ESD Robustness	5kV HBM rating - withstands handling and board assembly without guard rings or external protection diodes.
Minimal External Components	Operates with only 0.001µF output capacitor - reduces BOM count and PCB area vs. references requiring multiple bypass caps or compensation networks.

Equivalent & Alternatives

The following parts are listed as comparable options for similar voltage reference applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
REF3040AIDBZR	4.096V, ±1.5mV initial accuracy, 50ppm/°C, 50µA supply current - higher power, lower accuracy grade than X60003CIG3Z-41.	Suitable for non-battery applications where 50µA is acceptable; lacks FGA™ long-term stability (100ppm/1000h vs. 50ppm).	Select when lower cost and wider distributor availability outweigh nanoscale power and superior aging performance.
ADR3440ARJZ-R7	4.096V, ±2mV initial accuracy, 10ppm/°C, 120µA supply current - tighter tempco but 240× higher current than X60003CIG3Z-41.	Preferred in temperature-stable lab equipment; unsuitable for >1-year battery life targets due to current draw.	Choose when thermal environment is tightly controlled and 10ppm/°C is mandatory, accepting trade-off in power consumption.

Compared with REF3040AIDBZR and ADR3440ARJZ-R7, the X60003CIG3Z-41 uniquely delivers 4.096V precision at 500nA - enabling decade-long battery life in remote sensors where alternatives consume >100× more current and exhibit faster long-term drift.

FAQ

What is the maximum input voltage for X60003CIG3Z-41?

The absolute maximum VIN to GND rating for X60003CIG3Z-41 is +10V, but the recommended operating input voltage range is 4.5V to 9.0V per the datasheet. Exceeding 9.0V may increase supply current nonlinearly and accelerate long-term drift; operation above 10V risks permanent damage to the internal FGA cell structure.

Does X60003CIG3Z-41 require an external capacitor on VOUT?

Yes, X60003CIG3Z-41 requires a minimum 0.001µF ceramic capacitor on VOUT for stability and noise reduction. Without it, output impedance rises above 100Ω at 1kHz, increasing susceptibility to PCB noise and degrading 30µV_P-P low-frequency noise performance. Larger capacitors (e.g., 0.01µF + 2kΩ series resistor) further reduce broadband noise to <40µV_P-P.

How does X60003CIG3Z-41 achieve such low supply current?

X60003CIG3Z-41 achieves 500nA typical supply current via Intersil's proprietary Floating Gate Analog (FGA™) technology, which stores precise charge on an isolated gate during fabrication - eliminating continuous bias current needed in bandgap or zener references. The output buffer operates in deep subthreshold CMOS mode, drawing current only for gate leakage and output loading.

Can X60003CIG3Z-41 drive a 10mA load directly?

Yes, X60003CIG3Z-41 is rated for ±10mA source/sink current. At 10mA sourcing, load regulation is ≤50µV/mA - resulting in ≤0.5mV output shift. However, dropout voltage increases to ~300mV at full load, so ensure VIN ≥ VOUT + 300mV (i.e., ≥4.396V) to maintain regulation. For sustained 10mA loads, verify junction temperature remains below +107°C.

Is X60003CIG3Z-41 sensitive to X-ray exposure?

Yes, X60003CIG3Z-41 is highly sensitive to X-ray exposure - doses as low as 10mRem can cause >10mV output shift. Post-assembly X-ray inspection must be avoided or shielded with ≥300µm zinc foil. Airport luggage scanners (especially checked baggage) pose cumulative risk; mounting behind two copper layers reduces dose by >90%, preserving initial accuracy.
