Features
• Ultra low offset voltage: 25 µV typ, 100 µV max
• Rail-to-rail input/output voltage swing
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 batterypowered 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).
• Operates from 2.7 V to 5.5 V
• High speed: 1.9 MHz
• 45° phase margin with 100 pF
• Low consumption: 0.8 mA at 2.7 V
• Very large signal voltage gain: 131 dB
• High-power supply rejection ratio: 105 dB
• Very high ESD protection 5kV (HBM)
• Latchup immunity
• Available in SOT23-5 micropackage
• Automotive qualification

1. Value with respect to VDD pin.
2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
3. VCC-Vin and Vin must not exceed 6 V.
4. Short-circuits can cause excessive heating and destructive dissipation.
5. Rthja/c 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.
