Applications
The LTC6652AHMS8-2.048 is ideal for precision data acquisition systems where a stable 2.048 V reference directly maps to 16-bit ADC full-scale without scaling. It is used in industrial instrumentation, medical diagnostic equipment, and precision weighing systems requiring long-term output voltage stability. The buffered output and low noise also make it suitable for high-resolution DAC references in calibration and test equipment.

Frequently Asked Questions
How stable is the LTC6652AHMS8-2.048 output over the full industrial temperature range?
The LTC6652AHMS8-2.048 maintains its 2.048 V output with a maximum temperature coefficient of 5 ppm/°C across the -40°C to 125°C industrial temperature range. Over the full range, this results in less than 0.43 mV total voltage deviation, which is adequate for 14-bit resolution data acquisition systems without requiring additional compensation.
Can LTC6652AHMS8-2.048 directly drive multiple ADC reference inputs without a buffer stage?
Yes. The buffered output can source and sink up to 5 mA, making it capable of driving several ADC VREF pins simultaneously. For a typical 16-bit SAR ADC drawing 1 mA during conversion, the LTC6652AHMS8-2.048 can supply at least 4 parallel ADC references without output voltage droop affecting conversion accuracy.
What is the output noise performance of the LTC6652AHMS8-2.048 and how does it affect 16-bit ADC accuracy?
The LTC6652AHMS8-2.048 exhibits low output noise of approximately 3 µV RMS in the 0.1 Hz to 10 Hz band, which is well below the 31 µV LSB step size of a 16-bit ADC referenced to 2.048 V. This ensures the reference noise contributes negligibly to overall system noise, preserving 16-bit measurement accuracy in sensitive instrumentation designs.
When is LTC6652AHMS8-2.048 preferred over a simple 2.5 V zener-based reference in precision designs?
Unlike a zener reference with typical 100 ppm/°C drift and high noise, the LTC6652AHMS8-2.048 offers 5 ppm/°C drift and a buffered low-impedance 2.048 V output. For 12-bit or higher resolution systems requiring initial accuracy better than 0.1% and stable long-term drift under 50 ppm, the IC reference eliminates the external buffer op-amp and trimming resistors that a zener solution requires.
