Description
The TS187x (single, dual & quad) is an
operational amplifier family able to operate with
voltage as low as 1.8V and features both I/O railto-rail.
The common mode input voltage extends 200mV
at 25°C beyond the supply voltages while the
output voltage swing is within 100mV of each rail
with 600 Ohm 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 performances make the TS187X family
ideal for sensor interface, battery-supplied and
portable applications.

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 Vid > ±1V, the maximum input current must not exceed ±1mA. In this case (Vid > ±1V) an input serie resistor must be added to limit input current.
3) Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuit on all amplifiers
4) Human body model, 100pF discharged through a 1.5kΩ resistor into pin of device.
5) Machine model ESD, a 200pF cap is charged to the specified voltage, then discharged directly into the IC with no external series resistor
