Description
The TS94x (single, dual and quad) series are
operational amplifiers characterized for 2.5 V to
10 V operation over a -40° C to +85° C
temperature range.
They exhibit excellent consumption -1.2 µA, while
featuring 10 kHz gain bandwidth product, 1.5 mA
output capability and output rail-to-rail operation
- 2.85 V typical at 3 V with R_L=10 kΩ.
The TS94x op-amps are ideal for battery-powered
systems, where very low supply current and
output rail-to-rail are required. Their very low
- 1 pA typical input bias current and constant
supply current over supply voltage enhance the
devices’ performance near the end of the battery
charge or battery life.
