Device Overview
Texas Instruments LM2903DR is an exact-order Dual differential comparator supplied in SOIC-8. Selection of this exact part is driven primarily by Device type (Dual differential comparator), Channel count (2), Supply range (2 V to 36 V single-supply family range).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Device type | Dual differential comparator | Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. |
| Channel count | 2 | Defines the number or arrangement of parallel signal/control paths and therefore the resources a replacement must provide. |
| Supply range | 2 V to 36 V single-supply family range | Defines DC current demand and therefore contributes to power consumption, rail loading and thermal burden. |
| Typical supply current | 0.4 mA per comparator | Defines DC current demand and therefore contributes to power consumption, rail loading and thermal burden. |
| Exact Package | SOIC-8 | Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility. |
Analog Selection Notes
2 is the stated channel count value. Defines the number or arrangement of parallel signal/control paths and therefore the resources a replacement must provide.
Exact Package is SOIC-8. Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
Device type is Dual differential comparator. Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. 2 V to 36 V single-supply family range is the stated supply range value. Defines DC current demand and therefore contributes to power consumption, rail loading and thermal burden.
At 0.4 mA per comparator, the typical supply current defines compatibility with the available board supply rail and the voltage range over which the stated device function is intended to operate.
