What are the key features of REF192ESZ-REEL?
- Precision 2.5 V output with ±2 mV accuracy (2.498 V to 2.502 V), enabling 12-bit and 16-bit ADC/DAC systems to achieve full-scale accuracy
- Micropower LDO architecture with ultra-low quiescent current, maximizing battery life in portable and remote sensor nodes
- 8-pin SOIC package (R-PDSO-G8) with industry-standard pinout, simplifying drop-in replacement in existing 2.5 V reference circuits
What is REF192ESZ-REEL used for?
The REF192ESZ-REEL is used as the precision voltage reference in high-resolution data acquisition systems, portable medical instruments, and industrial calibration equipment where ADC full-scale accuracy depends on a stable 2.5 V reference. Its micropower consumption makes it suitable for battery-powered sensor nodes and remote data loggers that must maintain accuracy across the full industrial temperature range. It is also deployed in digital-to-analog converter circuits and strain-gauge bridges where long-term output stability directly impacts measurement quality.

Frequently Asked Questions
What output voltage accuracy does REF192ESZ-REEL provide, and is it suitable for 16-bit ADC references?
The REF192ESZ-REEL holds its output between 2.498 V and 2.502 V, corresponding to a ±2 mV or ±0.08% initial accuracy. For a 16-bit ADC with a 2.5 V reference, 1 LSB equals approximately 38 µV, so the ±2 mV initial error represents roughly 53 LSBs of offset. This is well within calibration range, and with system-level offset correction the device supports 16-bit accuracy in precision data acquisition designs.
How does the micropower consumption of REF192ESZ-REEL benefit battery-powered sensor designs?
The REF192ESZ-REEL draws only 45 µA of quiescent current at 2.5 V output, which amounts to just 112.5 µW of standby power. In a remote sensing node running on a 1000 mAh Li-ion cell, this allows the reference to remain powered continuously for over 22000 hours without depleting the battery, enabling always-on precision measurement without sleep-cycle complexity.
Can REF192ESZ-REEL replace a competing 2.5 V reference in an existing 8-pin SOIC footprint?
Yes. The REF192ESZ-REEL uses the standard 8-pin SOIC (R-PDSO-G8) package with the conventional 3-terminal voltage reference pinout, so it is pin-compatible with many industry-standard 2.5 V references in the same package. Its output accuracy of ±2 mV and operating input voltage down to 2.7 V make it a direct replacement candidate in designs originally built around devices such as REF192 in equivalent packaging, requiring no PCB changes.
