Description
The TSV358 and TSV324 (dual and quad) are low voltage versions of the LM358 and LM324 commodity operational amplifiers . The TSV321 is the single version. The TSV321/358/324 are able to operate with voltages as low as 2.5 V and feature both I/O rail-to-rail.

devices offer 1.3 MHz of gain-bandwidth product and provide high output current capability with a typical value of 80 mA.
These features make the TSV3xx family ideal for active filters, general purpose low-voltage applications, and general purpose portable devices.

1. All voltages values, except differential voltage are with respect to network terminal.
2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. If V
> ±1 V, the maximum input current must not exceed ±1 mA. When Vid > ±1 V, an input series resistor
id
must be added to limit input current.
3. Short-circuits can cause excessive heating and destructive dissipation. Rth are typical values.
4. Human body model: 100pF discharged through a 1.5 kΩ resistor between two pins of the device, done for all couples of pin combinations with other pins floating.
5. Machine model: a 200pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 combinations with other pins floating.
6. Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to the ground.
7. Short-circuits from the output to VCCcan cause excessive heating. The maximum output current is approximately 80 mA, independent of the magnitude of V simultaneous short-circuits on all amplifiers.
