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.All voltages values, except differential voltage are with respect to network ground terminal.

2.Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. If Vid > ±1V, the maximum input current must not exceed ±1mA. In this case (Vid > ±1V) an input serie resistor must be added to limit input current.

3.Do not exceed 14V.

4.Human body model, 100pF discharged through a 1.5kΩ resistor into pin of device.

5.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 < 5Ω), into pin to pin of device.

6.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 80mA, independent of the magnitude of Vcc. Destructive dissipation can result from simultaneous short-circuits on all amplifiers.
