Overview
The REF3120AIDBZTG4 is a series voltage reference IC manufactured by Texas Instruments, housed in an SOT-23-3 package. It provides a fixed output voltage of 2.048V with an initial accuracy of ±0.2% and a temperature coefficient of 20ppm/°C. The device operates within an input voltage range of 2.098V to 5.5V and draws a supply current of 135µA. It supports a maximum output current of 10mA and functions across a temperature range of -40°C to +125°C. Noise specifications include 27µVp-p from 0.1Hz to 10Hz and 39µVrms from 10Hz to 10kHz.
Feature Summary
- Delivers a stable fixed output voltage of 2.048V with high initial accuracy.
- Features low noise performance suitable for precision analog applications.
- Operates efficiently with a supply current of 135µA.
Applications
- Precision data acquisition systems
- Portable instrumentation
- Battery-powered measurement devices
Procurement Notes
Verify the specific suffix 'G4' against the manufacturer's latest documentation to confirm RoHS compliance status and lead times. Confirm package availability as distribution channels may list standard tape-and-reel options separately. Ensure the component meets environmental regulations required for your target market before finalizing procurement orders.
Selection Notes
Select this component when a precise 2.048V reference is required in a compact SOT-23-3 footprint. It is suitable for designs needing low power consumption and moderate noise levels. Compare against the REF3120AIDBZR variant if different packaging quantities are preferred. Ensure the input voltage remains above 2.098V for proper regulation.
Part Context
This part belongs to the REF31xx family of voltage references from Texas Instruments, designed for general-purpose precision applications. It shares architectural similarities with other members like the REF3112 and REF3125, differing primarily in output voltage and specific noise characteristics. The family targets cost-sensitive, space-constrained electronic designs requiring reliable voltage standards.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative components such as the REF3120AIDBZR based on pinout and electrical specifications before substitution.
