INA217 Low-Noise Instrumentation Amplifier for PLC Industrial Automation Applications
On this page
Thirty INA217-marked amplifier ICs are recorded as new in this Burr-Brown delivery of 6 January 2026. The photographs show loose eight-lead dual-in-line packages on foam, with a boxed BB logo, INA217 text and several different secondary codes. This is a component lot for circuit assembly or repair, with no assembled PLC interface board shown.
Identification and delivery details
The overview arranges the chips in three rows. Close photographs show the moulded orientation dots, two rows of four leads and top markings. Readable secondary codes include 39W842B, 39W868B, 39W841B, 39W840B and 3AWF1FB. They vary across the lot; this record does not claim that all thirty devices share one production code.
Several views turn one device over to show the underside and lead form. Some top surfaces have visible scuffs and unevenly legible markings. The record calls the goods new, while the photographs preserve those cosmetic details for a buyer to assess. Printed brand and type markings identify what the camera shows; they do not establish electrical noise performance or traceable factory provenance.

The delivery photographs establish the visible package and markings. For circuit design, TI's INA217 product documentation describes the original low-noise instrumentation amplifier and its audio applications; the INA217 datasheet gives the DIP-8 pinout and operating limits. Those specifications are design references, not measured results for this lot.
Matching this part
Compare the board footprint, pinout and required ordering suffix before buying loose ICs. The photographed top marking reads INA217 without a visible full orderable suffix. Confirm the exact package grade and acceptance requirements with the supplier.
The original INA217 is used for low-level differential signal amplification, including microphone circuits. A PLC-related use would need a separately designed analogue circuit; the loose chip itself does not provide a field-ready industrial input interface. Check the design documentation rather than treating the article title as an application qualification.
Photos and recorded media
Recorded inspection clip. The clip is retained as delivery evidence; no performance measurement is inferred from it.
