Description
The TS94x (single, dual & quad) series are
operational amplifiers characterized for 2.5V to
10V operation over -40°C to +85°C temperature
range.
They exhibit excellent consumption - 1.2µA, while
featuring 10kHz gain bandwidth product, 1.5mA
output capability and output rail-to-rail operation -
2.85V typ @ 3V with RL=10kΩ.
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 -
1pA typ input bias current and constant supply
current over supply voltage enhance TS94x’s
performance near the end of the life battery
charge.
Applications
n Battery-powered systems (alarm)
n Portable communication systems (pagers)
n Smoke/gas/fire detectors
n Instrumentation & sensoring
n PH meter
