Overview
The AD680ARZ-REEL7 is a band gap voltage reference providing a fixed 2.5 V output from input voltages between 4.5 V and 36 V. It features a maximum quiescent current of 250 μA, an initial accuracy of ±5 mV (±0.20%), and a temperature coefficient of 20 ppm/°C. The device operates within a specified temperature range of -40°C to +85°C. Noise performance includes 8 μV p-p from 0.1 Hz to 10 Hz and 250 nV/√Hz wideband spectral density. It is housed in an 8-lead SOIC package.
Feature Summary
- Laser trimmed for high initial accuracy and low temperature drift without external components
- Low noise characteristics suitable for precision data converter applications
- Integrated temperature output pin on 8-lead packages enabling transducer configuration
Applications
- Reference for ADCs and DACs requiring external precision voltage sources
- Hand-held and battery-operated equipment due to low power consumption
- Portable equipment power supplies requiring stable regulation
Procurement Notes
Verify the specific suffix 'REEL7' indicates tape and reel packaging containing 1,000 units per manufacturer specifications. Confirm the 'AR' grade corresponds to the -40°C to +85°C operating range and ±5 mV accuracy. Ensure compatibility with 8-lead SOIC footprint dimensions during PCB layout.
Selection Notes
Select this component when a complete, laser-trimmed band gap reference is required for low-power systems. The AR grade offers superior accuracy compared to JR grades. Consider the integrated temperature pin if environmental monitoring is needed alongside voltage referencing.
Part Context
The AD680 series provides a cost-effective alternative to standard two-terminal references while delivering higher accuracy. It merges the amplifier and core band gap function into a compact design. The AR variant specifically targets industrial applications requiring extended temperature stability and tight initial tolerance.
Replacement Considerations
AD680ARZ-REEL7 serves as a direct replacement for AD680AR-REEL7 in reel configurations. Verify pinout compatibility with existing designs utilizing other AD680 variants.
