Quad op-amp for automotive signal chains
The STMicroelectronics TS9224IDT is a quad-channel, general-purpose operational amplifier from the Automotive, AEC-Q100 series — qualified to the automotive reliability standard, not just rated to an extended temperature range. Supply range spans 2.7 V to 12 V, covering both low-voltage logic rails and battery-referenced circuits.
For designs that only need industrial temperature range, the non-automotive TS922 or TS924 series may be cost-optimised, but they lack the qualification traceability an automotive auditor expects.
Package and footprint for production
Supply current is 900 µA per amplifier — a reasonable quiescent budget for a multi-channel sensor interface on a 12 V battery line.
