SINGLE LOW-POWER 1.8V RAIL TO RAIL INPUT AND OUTPUT
OPERATIONAL AMPLIFIERS WITH SHUTDOWN
DESCRIPTION
UTC LV981 is a low-voltage, low-power operational amplifier
with shutdown function. UTC LV981 has rail-to-rail input/output,
and operates from 1.8V to 5V voltage. So it suits for low-voltage
and portable applications. UTC LV981 input common mode
voltage extends 200mV beyond the supplies which enables user
enhanced functionality beyond the supply voltage range. The
output can swing rail-to-rail unloaded and within about 105mV
from the rail with 600Ω load at 1.8V supply. UTC LV981 can work
at 1.8V, which makes it ideal for portable two-cell battery powered
systems or single cell Li-Ion systems.
UTC LV981 offers shutdown function so that can realize power
saving. The device is in shutdown when the SHDN pin pull to
low. The output is high impedance in shutdown.
UTC LV981 show excellent speed-power ratio, when powering
1.8V supply, it performs 1.4MHz gain bandwidth product with low
supply current 100µA.
