The TS187x (single, dual & quad) is an
operational amplifier family able to operate with
voltages as low as 1.8V and features both input
and output rail-to-rail.

The common mode input voltage extends 200mV
beyond the supply voltages at 25°C while the
output voltage swing is within 100mV of each rail
with 600Ω load resistor. This device consumes
typically 400µA per channel while offering 1.6MHz
of gain-bandwidth product. The amplifier provides
high output drive capability typically at 65mA load.
These features make the TS187x family ideal for
sensor interface, battery-supplied and portable
applications.

1. All voltage 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 Vid > ±1V, the
maximum input current must not exceed ±1mA. When Vid > ±1V, add an input series resistor to limit input current.
3. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuits on all
amplifiers.
4. Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a 1.5kΩ resistor
between two pins of the device. This is done for all couples of connected pin combinations while the other pins are 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 < 5Ω). This is done for all couples of connected pin combinations
while the other pins are floating.
6. 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.
7. 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.

In order to meet environmental requirements, STMicroelectronics offers these devices in
ECOPACK® packages. These packages have a lead-free second level interconnect. The
category of second level interconnect is marked on the package and on the inner box label,
in compliance with JEDEC Standard JESD97. The maximum ratings related to soldering
conditions are also marked on the inner box label. ECOPACK is an STMicroelectronics
trademark. ECOPACK specifications are available at: www.st.com.
