Key Features
- 2.5 V output trimmed to 0.05% initial accuracy (2.4987 V to 2.5012 V window) provides a stable ADC reference for 16-bit and 18-bit data-acquisition systems without post-calibration
- Ultra-low noise specification allows direct connection to SAR and delta-sigma ADC reference inputs where noise floor dominates system dynamic range at sampling rates up to 1 MSPS
- 8-pin MSOP package with single 3.0 V to 13.2 V input range integrates seamlessly with 3.3 V and 5 V mixed-signal boards, minimizing external bypassing to a single 10 µF capacitor
Applications
LTC6655CHMS8-2.5#PBF serves as the voltage reference in precision data-acquisition systems, medical instrumentation, and industrial process controllers where ADC full-scale error must remain below 1 LSB at 16-bit resolution. Its low noise density is critical in audio measurement equipment and scientific instruments that sample slowly varying signals at 24-bit resolution. The device also provides a stable 2.5 V reference for precision DACs in automatic test equipment and programmable power supplies.

Frequently Asked Questions
What initial accuracy does LTC6655CHMS8-2.5#PBF guarantee, and how does it map to LSB error in a 16-bit ADC system?
The device guarantees a maximum initial error of 0.05%, which at 2.5 V corresponds to ±1.25 mV. For a 16-bit ADC with a 2.5 V full-scale reference, 1 LSB equals 38 µV; a 1.25 mV reference error introduces approximately 33 LSBs of full-scale offset—well within the range correctable by a single system calibration, and smaller than the uncorrected error of typical 0.1% references.
How does LTC6655CHMS8-2.5#PBF perform in a battery-powered precision instrument operating across a wide temperature range?
LTC6655CHMS8-2.5#PBF features a low temperature coefficient, typically below 5 ppm/°C, keeping reference drift below 0.2 mV across a 0 °C to 70 °C commercial operating range. In a 16-bit system, this 0.2 mV drift corresponds to about 5 LSBs of full-scale shift—within the error budget of most calibrated portable instruments and superior to 25 ppm/°C references used in lower-grade designs.
What bypass capacitor is recommended for LTC6655CHMS8-2.5#PBF to achieve specified noise performance at the ADC reference pin?
Analog Devices recommends a 10 µF bypass capacitor at the output pin to the reference return, combined with a 100 nF ceramic capacitor placed within 2 mm of the MSOP package. This RC filter rolls off reference noise above 1 kHz, reducing the broadband noise contribution to below 3 µV RMS in the 0.1 Hz to 10 Hz band—sufficient for 18-bit to 20-bit delta-sigma ADCs sampling below 10 kSPS.
