DESCRIPTION
The TS94x (Single, Dual & Quad) is Operational
Amplifier characterized for 2.7V to 10V operation
over -40
C to +85
C temperature range.
It is exhibiting an excellent consumption - 1.2
A,
while featuring 10kHz gain bandwidth product,
1.5mA output capability and output Rail to Rail op-
eration - 2.85V typ @ 3V with RL=10k
.
The TS94x Op-Amp is ideal for battery-powered
systems, where very low supply current and out-
put Rail to Rail are required. Its very low - 1pA typ
input bias current and constant supply current
over supply voltage enhance TS94x's perfor-
mance near the end of the life battery charge.

1. All voltages values, except differential voltage are with respect to network terminal.
2. Differential voltages are non-inverting input terminal with respect to the inverting input terminal.
3. The magnitude of input and output voltages must never exceed V
CC
+0.3V.
4. Short-circuits can cause excessive heating and destructive dissipation.
