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-
put voltage swing is within 100mV of each Rail for a
600
load resistor. This I/O Rail to Rail configura-
tion 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 & 400
A supply
current, this Op-Amp is very well-suited for bat-
tery-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.

Notes : 1. All voltage values, except differential voltage are with respect to network ground terminal.
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 V
CC
+0.3V.
4. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuit on all amplifiers.
