Product details
Overview
X60008BIS8-25T1 from Intersil is a precision 2.5V floating-gate analog (FGA™) voltage reference with ±0.5mV initial accuracy, 3ppm/°C temperature coefficient, and ultra-low 500nA supply current. It delivers 10mA source/sink capability, 10ppm/1000hrs long-term stability, and operates from 4.5V to 6.5V over –40°C to +85°C - enabling high-resolution data acquisition in battery-powered portable instrumentation.
For engineers reviewing the X60008BIS8-25T1 datasheet, X60008BIS8-25T1 pinout, X60008BIS8-25T1 application, or X60008BIS8-25T1 equivalent, key selection criteria include nanoscale power budgeting, sub-millivolt DC accuracy under thermal cycling, low-noise 30µVPP (0.1–10Hz), and SOIC-8 compatibility for space-constrained precision analog signal chains.
Technical Context
The X60008BIS8-25T1 uses Intersil's proprietary Floating Gate Analog (FGA™) technology - not bandgap or buried zener - to achieve stable 2.500V output via charge-trapped floating gate cell buffered by CMOS circuitry. Its architecture eliminates conventional voltage-reference drift mechanisms while enabling programmable output voltages beyond standard values.
This device features a 3ppm/°C box-method temperature coefficient, 50ppm thermal hysteresis, and 100µV/V line regulation across 4.5–6.5V input. Load regulation is specified at ±10µV/mA (sourcing) and ±20µV/mA (sinking) over 0–10mA, with turn-on time of 7ms typical and up to 12ms at minimum supply current.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6126AASA25+ | 2.5V, ±0.02% (±0.5mV), 3ppm/°C, but 1.1µA supply current - more than double X60008BIS8-25T1. | Suitable for higher-speed systems needing faster turn-on (<100µs); less optimal for multi-year battery life. | Select when system clocking or sequencing demands sub-millisecond wake-up, not ultra-low power. |
| ADR3425ARJZ-R7 | 2.5V, ±0.1% (±2.5mV), 10ppm/°C, 3.5µA supply current - lower accuracy and higher power than X60008BIS8-25T1. | Better suited for cost-sensitive industrial controls where 0.1% accuracy suffices and PCB area is constrained. | Select when BOM cost is prioritized over metrology-grade accuracy and battery runtime. |
Compared with MAX6126AASA25+ and ADR3425ARJZ-R7, the X60008BIS8-25T1 uniquely combines ±0.5mV accuracy, 3ppm/°C tempco, and 500nA supply current - making it the only option for battery-operated 24-bit data loggers requiring annual calibration intervals and >5-year shelf life.

FAQ
What is the guaranteed initial accuracy of the X60008BIS8-25T1 over temperature?
The X60008BIS8-25T1 has guaranteed initial accuracy of ±0.5mV at 25°C, with total output variation of ±0.5mV across –40°C to +85°C due to its 3ppm/°C temperature coefficient - resulting in ≤0.39mV additional drift over the full range. This specification is verified per the box method defined in the datasheet and applies to every shipped unit.
Does the X60008BIS8-25T1 require external capacitors for stability?
Yes - the X60008BIS8-25T1 requires a 0.001µF capacitor between VOUT and GND for basic stability and noise reduction. For broadband noise suppression (1Hz–1MHz), the recommended network is a 2kΩ resistor in series with a 10µF capacitor, plus a 0.01µF capacitor from VOUT to GND, as shown in Figure 3 of the FN8140.1 datasheet. Omitting these degrades noise performance and may cause oscillation under load.
Can the X60008BIS8-25T1 drive a 10kΩ load directly?
Yes - the X60008BIS8-25T1 can drive a 10kΩ load (250µA at 2.5V) with minimal error: load regulation is specified at ±10µV/mA for sourcing, so 250µA introduces ≤2.5µV error - well within its ±0.5mV initial accuracy. For loads below 1kΩ, verify output impedance vs. frequency using the ZOUT vs. Frequency curve on page 6 of FN8140.1.
Is the X60008BIS8-25T1 pin-compatible with other members of the X60008 family?
Yes - all X60008 variants (X60008B/C/D) share identical 8-lead SOIC pinout and footprint (MDP0027). The X60008BIS8-25T1 differs only in grade (±0.5mV/3ppm), while X60008CIS8-25T1 offers ±0.5mV/5ppm and X60008DIS8-25T1 offers ±1.0mV/10ppm - allowing drop-in replacement based on accuracy/tempco trade-offs without layout change.
What is the maximum safe input voltage for the X60008BIS8-25T1?
The absolute maximum input voltage for the X60008BIS8-25T1 is +6.5V applied to VIN relative to GND. Exceeding this risks permanent damage. The recommended operating range is 4.5V to 6.5V; operation below 4.5V may cause output dropout or increased noise. Input voltage must never go negative relative to GND beyond –0.5V.
