AT-MIO-16L-25

The National Instruments AT-MIO-16L-25 is a legacy multifunction data acquisition board in the AT-MIO-16L family for PC/AT systems. The official family manual covers analog I/O, digital I/O, timing signals, and hardware configuration; the -25 variant's sampling performance requires separate confirmation.

Overview

Product overview

Key product information and technical features.

The AT-MIO-16L family combines analog acquisition with analog output, digital I/O, and timing functions on an AT-bus board. Its analog input circuitry supports differential and single-ended wiring, with programmable gain for adapting the input path to the signal.

Integration involves hardware configuration rather than assuming automatic resource assignment. The family manual describes base I/O address, DMA, interrupt, and analog I/O settings, as well as signal wiring. Confirm the installed board revision and exact variant before applying performance limits.

AT-MIO-16L family analog input supports 16 single-ended or 8 differential channels.
12-bit analog input conversion is documented for the AT-MIO-16L family.
Software-selectable input gains of 1, 10, 100, and 500 distinguish the L-family input path.
Official family documentation includes analog output, digital I/O, timing, and RTSI signal connections.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

How many analog inputs does the AT-MIO-16L family support?

NI documents 16 single-ended or 8 differential analog inputs with 12-bit resolution for the AT-MIO-16L family.

What input gains are documented for the L family?

The AT-MIO-16L family has software-selectable gains of 1, 10, 100, and 500. Input range and wiring configuration must also be considered when configuring measurements.

Does the linked family manual establish the -25 variant's maximum sampling rate?

The reviewed manual does not explicitly identify the AT-MIO-16L-25 variant. Its family-level sampling-rate figure should not be treated as a verified -25 specification.
