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.
The common mode input voltage extends 200 mV
beyond the supply voltages at 25° C while the
output voltage swing is within 100 mV of each rail
with a 600
Ω
load resistor. At V
CC
= 3 V, these
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
id
> ±1 V, the maximum input current must not exceed ±1 mA. When V
id
> ±1 V, an input series resistor
must be added to limit input current.
3. Short-circuits can cause excessive heating and destructive dissipation. R
th
are typical values.
4. Human body model: 100 pF discharged through a 1.5 k
Ω
resistor between two pins of the device, done for
all couples of pin combinations with other pins floating.
5. 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
), done for all couples of pin
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 V
CC
can cause excessive heating. The maximum output current is
approximately 80 mA, independent of the magnitude of V
CC
. Destructive dissipation can result from
simultaneous short-circuits on all amplifiers.
