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 RL=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.
