TLV521DCKR

UMW · Operational Amplifier · SC-70-5

TLV521DCKR from UMW, in a SC-70-5. 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 OUT output Op-amp output. Rail-to-rail output capable of sourcing ~11 mA and sinking ~12 mA into loads referenced within the V+/V- supply range.
2 V- power_in Negative power supply rail. Typically tied to GND for single-supply operation; total supply (V+ - V-) between 1.7 V and 5.5 V.
3 IN+ input Noninverting input. High-impedance CMOS input with ~1 pA typical input bias current; rail-to-rail input common-mode range.
4 IN- input Inverting input. High-impedance CMOS input with ~1 pA typical input bias current; rail-to-rail input common-mode range.
5 V+ power_in Positive power supply rail. Operating range 1.7 V to 5.5 V relative to V-; absolute maximum 6 V relative to V-.

  • 3D model files: tlv521dckr-etched.step / tlv521dckr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlv521dckr.step / tlv521dckr.glb are the bare package body.

Provenance

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

  • Datasheet: UMW datasheet (11 pp, sha256 ea34bdb7f34d8333, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
