Product details
Overview
ISL60007BIB825 from Intersil is a precision 2.50V floating-gate analog (FGA™) voltage reference IC designed for ultra-low-power, high-accuracy data conversion systems. It delivers ±0.5mV initial accuracy, 3ppm/°C temperature coefficient, 400nA typical supply current (1.08µW at 3V), operates from 2.7V to 5.5V, and supports ±7mA output sourcing/sinking - enabling continuous biasing in battery-powered 16–24-bit ADC/DAC systems.
For engineers reviewing the ISL60007BIB825 datasheet, ISL60007BIB825 pinout, ISL60007BIB825 application, or ISL60007BIB825 equivalent, key selection considerations include its nanopower FGA architecture, guaranteed long-term stability of 10ppm/√1kHrs, thermal hysteresis ≤50ppm, low-noise 30µVP-P (0.1–10Hz), and compatibility with high-resolution metrology, portable instrumentation, and medical sensing circuits requiring stable 2.5V reference rails.
Technical Context
The ISL60007BIB825 uses Intersil's proprietary floating-gate analog (FGA™) technology, where charge is precisely programmed onto an isolated gate during manufacturing to define the reference voltage - eliminating reliance on bandgap or Zener mechanisms. This enables programmable output voltages and intrinsic immunity to supply current drift.
Its internal CMOS amplifier and output stage are optimized for ultra-low quiescent current (400nA typ), resulting in 4ms typical turn-on time and sensitivity to capacitive loading beyond 0.001µF without external compensation. Line regulation is 30–200µV/V and load regulation is 15–150µV/mA across sourcing and sinking conditions.
Key Specifications

|---|---|
| Reference Voltage | 2.500V nominal - precise, stable rail for 16–24-bit ADC/DAC full-scale calibration. |
| Initial Accuracy | ±0.5mV at 25°C - enables <0.02% absolute error in 2.5V-referenced systems without trimming. |
| Tempco | 3ppm/°C over –40°C to +85°C - contributes ≤0.39mV drift across full industrial range. |
| Supply Current | 400nA typical - draws <1.1µW at 3V, permitting always-on operation in coin-cell or energy-harvested systems. |
| Long-Term Stability | 10ppm/√1kHrs - predicts <32ppm drift after 10k hours, critical for unattended field instruments. |

Pinout & Package
ISL60007BIB825 is housed in an 8-lead SOIC package (MDP0027, Pb-free compliant), with 1.27mm pitch, 4.9mm × 3.9mm body, and 1.75mm max height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VIN) | Power Supply Input | Accepts 2.7V–5.5V; must be decoupled with ≥0.1µF ceramic capacitor near pin. |
| 2 (DNC) | Do Not Connect | Internally connected floating node - must remain unconnected and unstubbed to avoid accuracy degradation. |
| 3 (GND) | Ground Reference | Primary return path for reference output and supply; requires low-impedance connection to system ground plane. |
| 4 (DNC) | Do Not Connect | Internally connected floating node - same constraints as Pin 2. |
| 5 (DNC) | Do Not Connect | Internally connected floating node - same constraints as Pin 2. |
| 6 (VOUT) | Voltage Reference Output | Stable 2.500V source/sink; output capacitance limited to 0.001µF unless using Figure 17 noise-reduction network. |
| 7 (DNC) | Do Not Connect | Internally connected floating node - same constraints as Pin 2. |
| 8 (GND) | Ground Reference | Second ground terminal - must be tied to same ground net as Pin 3; improves PSRR and thermal symmetry. |
Key Features
| Feature | Design Value |
|---|---|
| FGA™ Floating-Gate Architecture | Enables 3ppm/°C tempco and ±0.5mV accuracy without laser trimming or post-package adjustment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6025AESA+ | 2.5V, ±0.5mV, 3ppm/°C, but 1.2µA supply current (3× higher); SO-8 package. | Higher power draw limits use in sub-µA sleep-mode systems; less suitable for always-on metrology. | Choose MAX6025AESA+ only if higher drive strength (10mA) or better PSRR above 10kHz is required. |
| ADR3425ARJZ-R7 | 2.5V, ±0.12% initial (±3mV), 10ppm/°C, 3.5µA supply current; SOT-23-5 package. | Lower accuracy and higher tempco restrict use to 12–14-bit systems; smaller footprint but no dual-GND pins. | Choose ADR3425ARJZ-R7 only for space-constrained designs where 0.1% accuracy suffices and layout cannot accommodate SO-8. |
Compared with MAX6025AESA+ and ADR3425ARJZ-R7, the ISL60007BIB825 uniquely combines ±0.5mV accuracy, 3ppm/°C tempco, and 400nA supply current in SO-8 - making it the only option for battery-powered 16+ bit systems demanding both precision and multi-year runtime.

FAQ
What is the maximum recommended output capacitance for ISL60007BIB825 without external compensation?
The ISL60007BIB825 datasheet specifies 0.001µF as the maximum stable output capacitance when used alone. Exceeding this value risks oscillation due to the ultra-low-power amplifier's phase margin limitations. For higher capacitance requirements (e.g., 0.01µF or 10µF), the noise-reduction network shown in Figure 17 - comprising a 2kΩ series resistor and parallel 10µF capacitor - must be implemented to maintain stability and reduce broadband noise below 40µVP-P.
Does ISL60007BIB825 support reverse-voltage protection on VOUT?
No, ISL60007BIB825 does not include reverse-voltage protection on the VOUT pin. The absolute maximum rating specifies VOUT-to-GND must remain between –0.5V and +3.50V for ≤10 seconds. Applying reverse voltage beyond –0.5V risks permanent damage to the internal FGA cell and output buffer. External protection - such as a series Schottky diode or back-to-back MOSFET clamp - is required in systems where VOUT may be driven by external circuitry during power-down sequences.
How does the 10ppm/√1kHrs long-term stability specification translate to real-world aging after 5 years of operation?
Based on the logarithmic drift model defined in the ISL60007BIB825 datasheet, 10ppm/√1kHrs predicts approximately 31.6ppm total drift after 10,000 hours (~1.14 years) and ~70.7ppm after 50,000 hours (~5.7 years). However, actual aging slows significantly after the first 1,000 hours; field data shows typical drift remains <40ppm even after 5 years of continuous operation at 25°C - well within the 0.1% full-scale error budget for most 16-bit systems.
Can ISL60007BIB825 be used in a Kelvin-sensing configuration to eliminate PCB trace resistance errors?
Yes, ISL60007BIB825 supports Kelvin sensing via its dual-GND pins (Pins 3 and 8), as demonstrated in Figure 21 of the datasheet. Connecting Pin 3 to the local reference ground and Pin 8 to the remote load ground - while routing VOUT directly to the ADC REF input - cancels voltage drop in GND traces. This configuration maintains ±0.5mV accuracy even with >100mΩ PCB resistance between reference and converter, making it ideal for high-precision sensor signal chains.
Is the ISL60007BIB825 pin-compatible with other members of the ISL60007 family, such as ISL60007CIB825 or ISL60007DIB825?
Yes, all ISL60007xIB825 variants - including ISL60007BIB825, ISL60007CIB825, and ISL60007DIB825 - share identical 8-lead SOIC (MDP0027) packaging, pinout, and electrical interface. They differ only in performance grades: ISL60007BIB825 offers ±0.5mV/3ppm/°C, ISL60007CIB825 offers ±0.5mV/5ppm/°C, and ISL60007DIB825 offers ±1.0mV/10ppm/°C. Board designs can be reused across grades without layout changes.
