Key Features
- Precision 3.0 V output with tight tolerance of plus or minus 10 mV (2.99 V to 3.01 V) ensures accurate ADC and DAC conversion with minimal calibration overhead
- Series reference topology rejects input supply noise and transients, delivering stable output even when input voltage varies over several volts
- Industry-standard SOIC-8 package simplifies drop-in replacement and layout reuse across multiple board generations
Applications
REF193GSZ-REEL serves as a stable 3.0 V reference for precision 12-bit to 16-bit ADCs and DACs in data acquisition systems, industrial instrumentation, and medical measurement equipment. Its low noise and tight output tolerance make it suitable for strain-gauge amplifiers, temperature transmitters, and calibration references in test and measurement boards. The SOIC-8 package integrates readily into mixed-signal PCBs requiring a compact, low-dropout voltage reference.

Frequently Asked Questions
How accurate is the 3.0 V output of REF193GSZ-REEL and how does that affect a 12-bit ADC measurement?
REF193GSZ-REEL specifies an output range of 2.99 V to 3.01 V, corresponding to a tolerance of plus or minus 10 mV. For a 12-bit ADC with a 3.0 V full-scale reference, this 0.33% tolerance contributes roughly 14 LSB of initial offset error. In precision applications, a one-time calibration at startup removes this fixed offset, leaving only drift over temperature as the residual error.
What minimum input voltage does REF193GSZ-REEL require to maintain a stable 3.0 V output?
REF193GSZ-REEL is a series (shunt-type linear) voltage reference that requires the input supply to exceed the 3.0 V output by the specified dropout voltage, typically around 200 mV to 400 mV. This means a minimum input of approximately 3.2 V to 3.4 V is needed for stable 3.0 V regulation, making it compatible with 3.3 V and 5 V supply rails common in embedded and industrial designs.
In which measurement applications is REF193GSZ-REEL preferred over a bandgap reference integrated inside a microcontroller?
On-chip bandgap references in microcontrollers typically have tolerances of 1% to 3% and temperature coefficients of 50 ppm/degree C to 200 ppm/degree C. REF193GSZ-REEL provides a tighter 0.33% initial accuracy and lower temperature drift, making it the preferred choice for 12-bit or higher ADC applications in industrial scales, medical oximeters, and precision sensor interfaces where measurement errors below 1 mV matter.
