DESCRIPTION

The TSM103 is a monolithic IC that includes one

independent op-amp and another op-amp for

which the non inverting input is wired to a 2.5V

fixed Voltage Reference. This device is offering

space and cost saving in many applications like

power supply management or data acquisition

systems.

1. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of

the common-mode voltage range is V

- 1.5V.

But either of both inputs can go to +36V without damage.
