Overview
The REF192FS-REEL7 is a micropower, low dropout voltage reference from the Analog Devices REF19x series. It provides a nominal output of 2.5 V with an initial accuracy of ±2 mV maximum and a temperature coefficient of 5 ppm/°C maximum. The device features a high output current capability of 30 mA and a low supply current of 45 μA maximum. It includes a sleep mode that reduces supply current to 15 μa maximum. The part operates over an extended industrial temperature range of −40°C to +85°C.
Feature Summary
- Utilizes patented temperature drift curvature correction circuitry for high stability
- Incorporates laser trimming of thin-film resistors to achieve precise initial accuracy
- Features a dedicated sleep pin for reducing power consumption in standby states
- Includes internal short-circuit protection for enhanced reliability
Applications
- Portable instruments
- ADCs and DACs
- Smart sensors
- Solar powered applications
- Loop-current-powered instruments
Procurement Notes
Verify the specific electrical grade (E, F, or G) required for the application, as performance specifications vary by grade. Confirm the package suffix matches the desired footprint, as the REF19x series is available in SOIC, TSSOP, and PDIP packages. Ensure the ordering suffix corresponds to the correct reel quantity and packaging format specified by the manufacturer.
Selection Notes
Select the appropriate electrical grade based on the required temperature coefficient and line regulation performance. Consider the input voltage range relative to the output voltage to ensure sufficient headroom for the low dropout operation. Evaluate the need for the sleep function if power conservation is critical for the system design.
Part Context
The REF192FS-REEL7 belongs to the REF19x series of precision band gap voltage references. This family is designed for applications requiring stable voltage references with low power consumption. The series offers various output voltages and packaging options to suit different design constraints.
Replacement Considerations
Other parts within the REF19x series may serve as alternatives depending on the required output voltage and package type. Verify compatibility regarding pin configuration and electrical specifications when substituting.
