Description
The TS924 is a rail-to-rail quad BiCMOS operational amplifier optimized and fully specified for 3V and 5V 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 or battery operated audio systems. The device is stable for capacitive loads up to 500pF .

1 Absolute Maximum Ratings
Table 1. Key parameters and their absolute maximum ratings
- All voltages values, except differential voltage are with respect to network ground terminal.
- Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. If Vid > ±1V,
added to limit input current.
- Human body model, 100pF discharged through a 1.5k Ω resistor into pin of device.
- Machine model ESD, a 200pF cap is charged to the specified voltage, then discharged directly into the IC with
no external series resistor (internal resistor < 5 Ω), into pin to pin of device.
- There is no short-circuit protection inside the device: short-circuits from the output to V cc
heating. The maximum output current is approximately 80mA, independent of the magnitude of V cc. Destructive dissipation can result from simultaneous short-circuits on all amplifiers. Table 2. Operating conditions

3 Macromodel
3.1 Important note concerning this macromodel
Please consider following remarks before using 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 (i.e. temperature, supply voltage, etc.). Thus the macromodel is often not as exhaustive as the datasheet, its goal is to illustrate the main parameters of the product.
- Data issued from macromodels used outside of its specified conditions (Vcc, Temperature, etc.) or even worse: outside of the device operating conditions (Vcc, Vicm, etc.) are not reliable in any way. In Section 3.3, the electrical characteristics resulting from the use of these macromodels are presented.
