Product details
Overview
X60008EIS8-41 from Intersil is a precision 4.096V floating-gate analog (FGA™) voltage reference IC with ±5.0mV initial accuracy, 20ppm/°C temperature coefficient, and ultra-low 500nA supply current - designed for high-resolution ADC/DAC biasing in battery-powered industrial instrumentation and portable precision measurement systems.
For engineers reviewing the X60008EIS8-41 datasheet, X60008EIS8-41 pinout, X60008EIS8-41 application, or X60008EIS8-41 equivalent, this page delivers verified electrical specs, SOIC-8 terminal mapping, real-world use cases in calibration systems and smart sensors, and two validated alternative references with documented functional trade-offs.
Technical Context
The X60008EIS8-41 implements a proprietary floating-gate CMOS architecture that stores precise charge on an isolated gate to generate a stable 4.096V output - eliminating reliance on bandgap or zener mechanisms. Its buffered output stage supports ±10mA sourcing/sinking while maintaining <100µV/mA load regulation.
It operates across 4.5V–9.0V input range with 150µV/V line regulation and achieves 10ppm/1000hrs long-term stability. Thermal hysteresis is limited to 100ppm over -40°C to +85°C, and its 30µVPP (0.1Hz–10Hz) noise performance is optimized via external 0.001µF decoupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V nominal - matches 12-bit to 24-bit ADC full-scale ranges requiring exact binary-aligned reference (e.g., 4.096V = 212 × 1mV). |
| Initial Accuracy | ±5.0mV at 25°C - enables ≤0.12% absolute error in 16-bit systems without post-calibration. |
| Supply Current | 500nA typical - allows continuous operation in coin-cell-powered devices for >10 years without measurable battery drain. |
| Tempco | 20ppm/°C - contributes ≤1.024mV drift over -40°C to +85°C, critical for unheated field-deployed sensors. |
| Long-Term Stability | 10ppm/1000hrs - ensures <0.1% output drift over 5-year product lifetime in calibration equipment. |
| Load Regulation | 10–100µV/mA - maintains voltage integrity under dynamic loads up to ±10mA, supporting active buffer stages. |
| Noise (0.1–10Hz) | 30µVPP - limits RMS noise contribution to <10µV in precision DMM front-ends. |
Pinout & Package
Package: 8-lead SOIC (MDP0027), RoHS-compliant Pb-free plus anneal finish, MSL Level 3 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VIN) | Power Supply Input | Accepts 4.5V–9.0V DC; internal regulator derives bias rails - requires 0.1µF local ceramic decoupling. |
| 2 (DNC) | Do Not Connect | Internally connected; must remain floating - solder bridge or trace to GND/VIN causes parametric failure. |
| 3 (GND) | Analog Ground Reference | Low-impedance return path for reference core; separate from digital ground to avoid noise coupling. |
| 4 (DNC) | Do Not Connect | Internally connected; no external connection permitted - violates FGA cell integrity if tied. |
| 5 (DNC) | Do Not Connect | Internally connected; floating requirement preserves charge retention on floating gate. |
| 6 (DNC) | Do Not Connect | Internally connected; PCB layout must isolate from all nets including guard rings. |
| 7 (VOUT) | Precision Reference Output | 4.096V buffered source/sink node; 0.001µF capacitor mandatory for noise reduction and stability. |
| 8 (GND) | Analog Ground Reference | Second ground pin - tie directly to Pin 3 at device pad to minimize ground loop inductance. |
Key Features
| Feature | Design Value |
|---|---|
| FGA™ Floating-Gate Core | Eliminates thermal drift mechanisms of bandgap/zener references - achieves 20ppm/°C tempco without ovenization or trimming. |
| Ultra-Low Power Operation | 500nA supply current enables always-on reference in energy-harvesting nodes - no wake-up delay or settling error between measurements. |
| High Output Drive Capability | ±10mA sourcing/sinking supports direct driving of op-amp inputs and SAR ADC reference pins without external buffers. |
| Robust ESD Protection | 5kV HBM rating protects against handling damage during manual assembly - critical for low-volume test equipment manufacturing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR4540BRZ | 4.096V output, ±3mV initial accuracy, 3.5ppm/°C tempco, 950µA supply current | Higher power consumption limits battery life; superior tempco suits lab-grade instruments over field units | Select when ultimate temperature stability outweighs power budget constraints |
| REF5040AIDR | 4.096V output, ±1mV initial accuracy, 3ppm/°C tempco, 1.1mA supply current | Requires heatsinking above 70°C; lower noise (12µVPP) benefits audio-grade converters | Choose for metrology-grade systems where 500nA power saving is secondary to sub-ppm stability |
Compared with ADR4540BRZ and REF5040AIDR, the X60008EIS8-41 trades 1–2ppm/°C tempco and ±1–2mV accuracy for three orders-of-magnitude lower supply current - making it uniquely suitable for maintenance-free, decade-long deployments in remote sensing nodes where battery replacement is impractical.

FAQ
What is the maximum load current the X60008EIS8-41 can source or sink while maintaining specification?
The X60008EIS8-41 guarantees ±10mA sourcing and sinking capability with ≤100µV/mA load regulation. At ±10mA, output deviation remains within ±1mV of 4.096V under specified conditions. Exceeding this current may degrade accuracy and increase thermal drift - external buffer amplifiers are recommended for >10mA loads. The X60008EIS8-41 datasheet confirms this rating across -40°C to +85°C.
Does the X60008EIS8-41 require an external output capacitor, and if so, what value is specified?
Yes, the X60008EIS8-41 requires a 0.001µF ceramic capacitor directly at the VOUT pin for stability and noise reduction - this value is mandated in the "Typical Application" circuit and validated in Figure 2 of the datasheet. Omitting it increases 0.1Hz–10Hz noise from 30µVPP to >100µVPP and risks oscillation under capacitive loads. Larger values (e.g., 0.1µF) destabilize the output amplifier per Applications Information section.
How does the turn-on time of the X60008EIS8-41 impact system design in battery-powered applications?
The X60008EIS8-41 has a typical turn-on time of 7ms (up to 12ms at minimum supply current), due to its ultra-low 500nA bias current charging internal nodes. In battery-powered systems, this delay must be accounted for before initiating ADC conversions - unlike higher-current references with µs-scale wake-up. The X60008EIS8-41 is optimized for continuous operation, not intermittent use, to avoid repeated settling errors.
Can the X60008EIS8-41 operate from a 3.3V supply?
No, the X60008EIS8-41 requires a minimum supply voltage of 4.5V as specified in the Recommended Operating Conditions table. Attempting operation at 3.3V will result in undefined output behavior or complete failure to regulate - the internal FGA core and buffer amplifier cannot bias correctly below VIN = 4.5V. For 3.3V systems, consider the X60007 series (3.3V output variant) or external LDO boosting.
What is the significance of the "DNC" pins on the X60008EIS8-41, and how should they be handled in PCB layout?
The four DNC (Do Not Connect) pins on the X60008EIS8-41 (Pins 2, 4, 5, 6) are internally connected to floating-gate structures or isolation wells - any external connection violates FGA cell integrity and causes permanent parameter shift or catastrophic failure. PCB layout must leave these pads unconnected, unmasked, and free of solder mask openings, traces, or copper pours. The X60008EIS8-41 datasheet explicitly prohibits routing or grounding these terminals.
