Description
The TS924 is a rail-to-rail quad BiCMOS
operational amplifier optimized and fully specified
for 3 and 5 V operation.
High output current allows low load impedances
to be driven.
The TS924 exhibits a very low noise, low
distortion, low offset and high output current
capability, making this device an excellent choice
for high-quality, low-voltage and battery-operated
audio systems.
The device is stable for capacitive loads up to
500 pF.

HBM: human body model(5)
5. 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.

6. 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.

Output short-circuit duration see note(8)
8. There is no short-circuit protection inside the device: short-circuits from the output to VCC can cause
excessive heating. The maximum output current is approximately 80 mA, independent of the magnitude of
VCC. Destructive dissipation can result from simultaneous short-circuits on all amplifiers.

3 Macromodel
3.1 Important note concerning this macromodel
You should note the following remarks before using this macromodel.
●All models are a trade-off between accuracy and complexity (that is, 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.
Section 3.2 presents the electrical characteristics resulting from the use of these
macromodels.
