Product details
Overview
X60008AIS8-50T1 from Intersil is a precision 5.0V floating-gate analog (FGA™) voltage reference IC with 1ppm/°C temperature coefficient, ±0.5mV initial accuracy, and ultra-low 800nA max supply current - designed for high-resolution data acquisition in battery-powered systems.
For engineers reviewing the X60008AIS8-50T1 datasheet, X60008AIS8-50T1 pinout, X60008AIS8-50T1 application, or X60008AIS8-50T1 equivalent, this device serves as a stable, low-drift, nanoscale-power reference for 16–24-bit ADCs/DACs, calibration systems, and precision regulators where long-term stability and thermal hysteresis <10ppm are critical.
Technical Context
The X60008AIS8-50T1 uses proprietary Floating Gate Analog (FGA™) technology to achieve sub-ppm/°C drift without bandgap or Zener constraints, enabling programmable output voltages and near-zero aging effects. Its CMOS-based output buffer supports ±10mA load regulation while maintaining 30µVp-p (0.1–10Hz) noise.
It operates from 5.1V to 9.0V input, delivers 5.000V nominal output with guaranteed line regulation of 20ppm/V and load regulation of 100µV/mA (sourcing), and features 80mA continuous short-circuit current capability with 5kV HBM ESD protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000 V ±0.5 mV at 25°C - enables direct interface with 5V-rail ADCs/DACs without gain trimming. |
| Tempco | 0.5–1.0 ppm/°C over –40°C to +85°C - ensures ≤125ppm total drift across industrial range, critical for metrology-grade accuracy. |
| Supply Current | 500 nA typical, 800 nA max - allows continuous biasing in multi-year battery applications (e.g., IoT sensors) with negligible drain. |
| Thermal Hysteresis | 10 ppm after ΔT = 25°C cycling - guarantees repeatable voltage after thermal excursions, essential for calibration standards. |
| Long-Term Stability | 10 ppm / 1,000 hours - provides predictable aging behavior for systems requiring >5-year unadjusted operation. |
| Output Noise | 30 µVp-p (0.1–10 Hz) - supports 20+ bit effective resolution when paired with low-noise signal chains. |
| Short-Circuit Current | 50–80 mA continuous - permits robust fault tolerance and safe driving of small capacitive loads without external limiting. |
Pinout & Package
Package: 8-lead SOIC (150 mil), RoHS-compliant Pb-free plus anneal finish (MDP0027).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VIN) | Power Supply Input | Accepts 5.1–9.0V DC; minimum headroom of 0.2V required for full 10mA sourcing at 85°C. |
| 2 (DNC) | Do Not Connect | Internally connected floating node; must remain unconnected to avoid parasitic coupling or instability. |
| 3 (GND) | Ground Reference | Low-impedance return path; requires dedicated ground plane connection to minimize thermal EMF errors. |
| 4 (DNC) | Do Not Connect | Internally connected floating node; PCB layout must isolate from traces and planes. |
| 5 (DNC) | Do Not Connect | Internally connected floating node; no external connection permitted per datasheet specification. |
| 6 (DNC) | Do Not Connect | Internally connected floating node; violation risks output drift or increased noise. |
| 7 (VOUT) | Voltage Reference Output | Buffered 5.000V source/sink; supports Kelvin sensing and drives up to 10mA with <100µV/mA load regulation. |
| 8 (GND) | Ground Reference | Second ground terminal for improved PSRR; must be tied to same ground net as Pin 3 with minimal trace length. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR4550BRZ | 5.0V, 3ppm/°C max, 1.2µA max supply current, SOIC-8 | Higher power and drift; lacks FGA™ long-term stability (20ppm/1,000hrs vs. 10ppm) | Preferred where higher PSRR (>120dB) and lower noise (1.8µVp-p) outweigh ultra-low power needs. |
| REF5050AIDR | 5.0V, 3ppm/°C max, 950µA max supply current, SOIC-8 | Orders-of-magnitude higher quiescent current; superior load regulation (3µV/mA) but unsuitable for battery use | Chosen for high-precision lab instrumentation where power is not constrained and load drive >20mA is required. |

FAQ
What is the maximum input voltage for the X60008AIS8-50T1?
The X60008AIS8-50T1 supports an absolute maximum input voltage of +10V, but its recommended operating range is +5.1V to +9.0V. Operating above +9.0V may increase supply current nonlinearly and degrade long-term stability. The device requires ≥0.2V headroom between VIN and VOUT to maintain full 10mA sourcing capability across temperature.
Does the X60008AIS8-50T1 require external capacitors for stability?
Yes - the X60008AIS8-50T1 requires at least a 0.001µF capacitor from VOUT to GND for optimal noise performance and transient response. For broadband noise reduction (1Hz–1MHz), the datasheet recommends a network: 2kΩ in series with 10µF to GND, plus a 0.01µF bypass directly at the output pin. Omitting output capacitance increases 0.1–10Hz noise to 30µVp-p and risks instability under dynamic loads.
How does the X60008AIS8-50T1 achieve 1ppm/°C temperature coefficient?
The X60008AIS8-50T1 achieves its 1ppm/°C tempco using Intersil's proprietary Floating Gate Analog (FGA™) technology, where charge is precisely trapped on a floating gate during manufacturing. This eliminates reliance on bandgap or Zener physics, enabling factory-trimmed drift performance verified via the "box method" over –40°C to +85°C. No external compensation or calibration is needed.
Can the X60008AIS8-50T1 sink current, and how much?
Yes, the X60008AIS8-50T1 can both source and sink up to ±10mA continuously while maintaining specified load regulation (≤100µV/mA). It also tolerates 80mA continuous short-circuit current without damage. Sink capability enables active pull-down in ratiometric sensor interfaces and bidirectional reference buffering in precision DAC output stages.
What is the turn-on time of the X60008AIS8-50T1, and why does it matter?
The X60008AIS8-50T1 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. This delay must be accounted for in systems performing rapid wake-up conversions - e.g., battery-powered data loggers - to avoid sampling before VOUT settles within 0.01% of final value.
