Active production — BOM-fit parameters
The TS321AILT is an active-production general-purpose op-amp from STMicroelectronics, described as a single-circuit enhanced version of the LM324/LM358 family. Operating from a single 3 V to 30 V supply span with 600 µA quiescent current, it suits battery-powered control boards and industrial 24 V rails alike.
Package and temperature grade
Housed in a 5-pin SOT-23-5 (SC-74A) surface-mount package, the footprint is compact enough for dense mixed-signal layouts — the 0.95 mm pin pitch routes easily on a two-layer board.
DC precision and output drive
Input offset voltage is 500 µV typical and input bias current is 20 nA — figures that allow direct coupling to high-impedance sources like thermistors or photodiodes without a nulling trim in many applications.
RoHS3 compliant.
