Frequently Asked Questions
What temperature drift specification makes the LTC6655LNCHMS8-2.5#PBF suitable for precision 18-bit ADC references?
The LTC6655LNCHMS8-2.5#PBF achieves an ultra-low temperature coefficient of 0.25 ppm/°C, which limits reference drift to less than 10 ppm over a 40 °C operating window. For an 18-bit ADC with a 2.5 V reference, a 10 ppm shift corresponds to roughly 0.26 LSB, ensuring the ADC remains within calibration across typical ambient temperature variations.
How does the 5 mA output current capability affect circuit design when multiple analog loads share the LTC6655LNCHMS8-2.5#PBF reference?
With a maximum output current of 5 mA, the reference can simultaneously drive the REF input of one or two 16-bit SAR ADCs while also supplying a precision DAC, provided total load stays below 5 mA. A low-dropout output buffer or reference distribution IC is recommended when more than 3 loads need to be driven to avoid degrading the 0.25 ppm/°C drift specification.
In what compact form factor does the LTC6655LNCHMS8-2.5#PBF ship, and how does it compare in board area to a SOT-23 reference?
The device is available in an MSOP-8 package with a footprint of approximately 3 mm × 3 mm, which is slightly larger than a SOT-23-5 but provides 8 pins for a dedicated output sense path, noise bypass, and trim connections. This additional pinout allows better noise filtering and trimming versus a 5-pin SOT-23 reference, making it preferable in high-resolution systems where the extra 2 mm² of board space is justified by the 0.25 ppm/°C performance.
