OptimWatt
TM
device featuring ultra-low
consumption, 2mW, and low quiescent
current, 400µA
Bandwidth: 120MHz (Gain=2)
Slew rate: 115V/µs
Specified on 1k
Input noise: 7.5nV/Hz
Tested on 5V power supply
Description
The TSH310 is a very low-power, high-speed
operational amplifier. A bandwidth of 120MHz is
achieved while drawing only 400µA of quiescent
current. This low-power characteristic is
particularly suitable for high-speed, battery-
powered equipment requiring dynamic
performance.
The TSH310 is a single operator available in SO8
and the tiny SOT23-5 plastic package, saving
board space as well as providing excellent
thermal performances.
Applications
Battery-powered and high-speed systems
Communication & video test equipment
Portable medical instrumentation
ADC drivers
