Frequently Asked Questions
How tight is the output voltage tolerance of the LT1461DHS8-2.5#PBF?
The LT1461DHS8-2.5#PBF guarantees an output voltage between 2.49625 V and 2.50375 V, a tolerance of ±3.75 mV around the 2.5 V nominal. This precision makes it suitable for driving the reference input of 12-bit or 16-bit ADCs where even small reference errors translate directly into conversion inaccuracies.
Can LT1461DHS8-2.5#PBF drive a 16-bit SAR ADC reference input directly?
Yes. The ±3.75 mV output tolerance corresponds to roughly ±0.15% accuracy at 2.5 V, which is well within the reference accuracy budget for 16-bit converters needing better than 1 LSB reference error. The SO-8 single-output reference can source sufficient current for most SAR ADC reference pins without external buffering.
What package does LT1461DHS8-2.5#PBF use and how many pins does it have?
The device uses an SO-8 (R-PDSO-G8) small outline package with 8 pins. The SO-8 footprint is widely supported by PCB assembly lines and offers a compact board area around 5 mm × 4 mm, making it practical for both industrial and consumer precision analog designs.
How does the LT1461DHS8-2.5#PBF perform in battery-powered portable instruments?
Its micropower LDO architecture draws very low quiescent current, extending battery runtime in portable instruments. The device maintains a stable 2.5 V output even as supply voltage drops close to the reference level, ensuring accurate ADC or DAC references throughout the battery discharge cycle from a nominal 3.3 V or 5 V supply.
