Product Description
The TS2123A/TS2124A families of products are low
noise, low voltage and low power operational
amplifiers with a gain-bandwidth product of 3.3MHz
and slew rate of 2V/μs. The maximum input offset
voltage is only 5mV and the input common mode
range extends beyond the supply rails.
TS2123A/TS2124A families of operational amplifiers
are specified at the full temperature range of
−40C to
+125C
under single or dual power supplies of 2.7V to
5.5V, however these products will operate under an
extended supply range from 2.7V to 5.5V at a
reduced temperatures range.
The TS2123A and TS2223A have a power-down
feature that reduces the supply current to 1μA.

ESD CAUTION
ESD (electrostatic discharge) sensitive device
Charged devices and circuit boards can
discharge without detection. Although this
product features patented or proprietary
protection circuitry, damage may occur on
devices subjects to high energy ESD. Therefore,
proper ESD precautions should be taken to
avoid performance degradation or loss of
functionality.
