Overview
The Analog Devices REF192GP is a micropower, low dropout voltage reference providing a nominal output of 2.5 V. It features a maximum temperature coefficient of 5 ppm/°C and an initial accuracy of ±2 mV. The device draws a maximum supply current of 45 μA and supports up to 30 mA output current. It operates within a temperature range of −40°C to +85°C and includes short-circuit protection.
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 mode pin for reducing supply current below 15 μA
Applications
- Portable instruments
- Analog-to-digital converters (ADCs)
- Digital-to-analog converters (DACs)
- Smart sensors
- Loop-current-powered instruments
Procurement Notes
Verify the specific electrical grade (E, F, or G) required for your application, as performance specifications vary by grade. Confirm package availability, noting that PDIP and TSSOP packages are restricted to the lowest electrical grade. Ensure compliance with RoHS standards before procurement.
Selection Notes
Select the REF192GP when a stable 2.5 V reference is needed in space-constrained designs requiring low power consumption. Consider the E grade for superior line and load regulation compared to F and G grades. Verify that the input voltage remains sufficiently above the output voltage to maintain regulation under maximum load conditions.
Part Context
The REF192GP belongs to the REF19x series of precision band gap voltage references manufactured by Analog Devices. This family offers various nominal output voltages tailored for different system requirements while maintaining consistent micropower characteristics and low dropout performance across the industrial temperature range.
Replacement Considerations
Direct replacements include other members of the REF19x series such as the REF192GRUZ-REEL7 or REF192GRU. When substituting, verify that the replacement part matches the required electrical grade and package type to ensure compatibility with existing board layouts and performance expectations.
