Product details

Precision 1.25 V reference for industrial bias chains

The TSM1014AIDT is a series voltage reference from STMicroelectronics delivering a fixed 1.25 V output with ±0.5% initial tolerance — tight enough to set the full-scale span for a 12-bit ADC without external trimming. Output current is rated 2.5 mA, sufficient to drive the reference input of multiple ADCs or DACs on the same bus while maintaining the 0.5% accuracy spec.

Temperature grade and supply current

The device draws 50 mA supply current from the input rail — this is the reference's own operating current, not the load current, and must be budgeted into the system power calculation alongside the 2.5 mA output capability. Packaged in the standard 8-SOIC footprint (3.90 mm body width), it mounts on the same PCB land pattern as an SOIC-8 op-amp or comparator, simplifying layout reuse.

ROHS3 compliant, meeting the current exemption-free restriction of hazardous substances directive for lead-free assembly.

Frequently asked questions

What is the tolerance of the TSM1014AIDT voltage reference?

The TSM1014AIDT offers ±0.5% initial tolerance on the 1.25 V fixed output. This is tighter than the sibling TSM1014IDT which is specified at ±1% — the AIDT suffix identifies the higher-grade bin.

Can TSM1014AIDT replace TSM1012AIDT on the same board?

Both parts share the same 8-SOIC package, 1.25 V fixed output, 4.5-28 V input range, and 2.5 mA output current capability. The TSM1014AIDT carries ±0.5% tolerance versus the TSM1012AIDT's ±0.5% — they are functionally identical for tolerance. The board layout and BOM position are interchangeable without rewiring.
