TS512, TS512A
Precision dual operational amplifier
Features
■Low input offset voltage: 500 µV max.
(A version)
■Low power consumption
■Short-circuit protection
■Low distortion, low noise
■High gain-bandwidth product: 3 MHz
■High channel separation
■ESD protection 2 kV
■Macromodel included in this specification
Description
The TS512 is a high-performance dual
operational amplifier with frequency and phase
compensation built into the chip. The internal
phase compensation allows stable operation in
voltage follower configurations, in spite of its high
gain-bandwidth product.
The circuit presents very stable electrical
characteristics over the entire supply voltage
range and is particularly intended for professional
and telecom applications (such as active filtering).

HBM: human body model(2)
2. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating.

3. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of
connected pin combinations while the other pins are floating.

4 Macromodels
4.1 Important notes concerning this macromodel
●All models are a trade-off between accuracy and complexity (i.e. simulation time).
●Macromodels are not a substitute to breadboarding; rather, they confirm the validity of
a design approach and help to select surrounding component values.
●A macromodel emulates the nominal performance of a typical device within specified
operating conditions (temperature, supply voltage, for example). Thus the
macromodel is often not as exhaustive as the datasheet, its purpose is to illustrate the
main parameters of the product.
Data derived from macromodels used outside of the specified conditions (VCC, temperature,
for example) or even worse, outside of the device operating conditions (VCC, Vicm, for
example), is not reliable in any way.
