DESCRIPTION
The TS187x (Single, Dual & Quad) is operational
amplifier able to operate with voltages as low as
1.8V and features both I/O Rail to Rail.
The common mode input voltage extends 200mV
@25°C beyond the supply voltages while the out-
putvoltageswingiswithin100mVofeachRailfor a
600Ω load resistor.This I/O Rail to Rail configuration gives the chance to the user to have the entire
supply voltage range available. Offering 20mA
min., 65mA typ. value and exhibiting an excellent
speed-power ratio, 1.6MHz GBP & 400µA supply
current, this Op-Amp is very well-suited for battery-supplied and portable applications.
Stability and minimum overshoot with capacitive
loads is maintained by 53° typ. of phase margin
with 100pF load capacitor @ 1.8V.

2. Differential voltages are the non-inverting input terminal with respect to the inverting terminal.
3. The magnitude of input and output voltages must never exceed VCC+0.3V.
4. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuit on all amplifiers.
