ST Life.augmented


Micropower, rail-to-rail 16V CMOS op-amps
  • active Active

The TSX63x and TSX63xA series of operational amplifiers offer low voltage operation and rail-to-rail input and output. TSX631 is the single version, TSX632 the dual version and TSX634 the quad version, with pinouts compatible with industry standards.

The TSX63x and TSX63xA series offer a 200 kHz gain bandwidth product while consuming 60 μA maximum at 16 V.

The devices are housed in the tiniest industrial packages.

These features make the TSX63x and TSX63xA family ideal for sensor interfaces and industrial signal conditioning. The wide temperature range and high ESD tolerance ease the use in harsh automotive applications.
