Circuit Description
The TS2902 made using four internally compensated, two-stage operational amplifiers. The first stage performs not
only the first stage gain function but also performs the level shifting and transconductance reduction functions. By
reducing the transconductance, a smaller compensation capacitor (only 5.0pF) can be employed, thus saving chip
area. Another feature of this input stage is that the input common mode range can include the negative supply or
ground, in single supply operation, without saturating either the input devices or the differential to single-ended
converter. The second stage consists of a standard current source load amplifier stage.
Each amplifier is biased from an internal-voltage regulator, and which has a low temperature coefficient thus giving
each amplifier good temperature characteristics as well as excellent power supply rejection.
