Quad 36 V precision rail-to-rail I/O op amp, 10 MHz, low offset and drift, TSSOP-14
The Texas Instruments OPA4197 is a quad 36 V precision operational amplifier with rail-to-rail input and output, 10 MHz gain-bandwidth and 20 V/µs slew rate. Offset is ±100 µV max at 25 °C with low drift, and it drives up to 1 nF capacitive loads. It is used in PLC analog I/O, test and measurement, grid protection, data acquisition and high-voltage industrial signal chains. Lead times are extended; Cerametronics helps buyers locate traceable stock.

Quality & Traceability
Cerametronics is ISO 9001 certified and products are RoHS compliant, with counterfeit screening and full traceability on every shipment. A Certificate of Conformance is available on request. For allocation-sensitive or high-risk lots, independent third-party lab verification can be arranged — just flag it on your RFQ. Any lot that fails incoming inspection is quarantined and never shipped.
FAQ
Is there a different package for OPA4197?
TI also offers the OPA4197 in SOIC-14 (D). It has a different footprint, so it is not a drop-in for the TSSOP-14 board layout.
Are there single and dual versions?
Yes. OPA197 (single) and OPA2197 (dual) share the same performance and can be used where fewer channels are needed.
