Description
The TS507 is a high performance rail-to-rail
input/output amplifier with very low offset voltage.
This amplifier uses a new trimming technique that
yields ultra low offset voltages without any need
for external zeroing.
The circuit offers very stable electrical
characteristics over the entire supply voltage
range, and is particularly intended for automotive
and industrial applications.
The TS507 is housed in the space-saving 5-pin
SOT23 package, making it well suited for battery-
powered systems. This micropackage simplifies
the PC board design because of its ability to be
placed in small spaces (external dimensions are
2.8 mm x 2.9 mm).

are typical values.
6. 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.
7. 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.
8. Charged device model: all pins and the package are charged together to the specified voltage and then
discharged directly to the ground through only one pin. This is done for all pins.
