Texas Instruments · Current Sense Amplifiers · SC-70-6

INA199B2QDCKRQ1 from Texas Instruments, in a SC-70-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 REF input Reference voltage input that sets the output zero level. Valid range 0V to V+. Drive from a low-impedance source (or ground for unidirectional low-side sensing).
2 GND power_in Device analog ground return.
3 V+ power_in Positive supply, 2.7V to 26V (absolute max 28V). Typical bypass 0.01µF-0.1µF from V+ to GND. Iq ≤ 100µA.
4 IN+ input Non-inverting current-sense input. Connect to the supply-side terminal of the external shunt resistor. Common-mode range -0.1V to 26V, independent of V+.
5 IN- input Inverting current-sense input. Connect to the load-side terminal of the external shunt resistor. Common-mode range -0.1V to 26V.
6 OUT output Analog voltage output. VOUT = REF + 100 × (VIN+ - VIN-) for the B2 variant (100V/V gain). Swings within the V+/GND rails.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (None pp, sha256 2df6a8494f6d9d8b, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
