General Description
The TS324 contains four independent high gain operational amplifiers with internal frequency compensation. The four
op-amps use a split power supply. The device has low power supply current drain, regardless or the power supply
voltage. The low power drain also makes the TS324 a good choice for battery operation.
When your project calls for a traditional op-amp function, now you can streamline your design with a simple single
power supply. Use ordinary +5V common to practically any digital system or personal computer application, without
requiring an extra 15V power supply just to have the interface electronics you need.
The TS324 is a versatile, rugged workhorse with a thousand-and-one uses, from amplifying signals from a variety of
transducers to dc gain blocks, or any op-amp function. The attached pages offer some recipes that will have your
project cooking in no time.
The TS358 is offered in 14 pin SOP-14 and DIP-14 package.

2. For supply. Voltages less than 32V for the PJ324 the absolute maximum input voltage is equal to the supply voltage.
3. This input current will only exist when the voltage is negative at any of the input leads. Normal output states will
reestablish when the input voltage returns to a voltage greater than -0.3V.

Notes :
1. The input common mode voltage or either input signal voltage should not be allowed to go negative by more than
0.3 V. The upper end of the common mode voltage range is Vcc 17V, but either or both inputs can go to +32V.
2. Short circuits from the output to Vcc can cause excessive heating and eventual destruction. Destructive dissipation
can recruit from simultaneous shorts on all amplifiers.

TS324 2-6 2003/12 rev. A
Circuit Description
The TS324 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.
