Each amplifier consumes only 330μA of current on a 3V
supply. The 10-lead DFN has an independent shutdown
function that reduces each amplifier’s supply current
to 1μA.
LTC6081/LTC6082 is specified for power supply voltages
of 3V and 5V from –40°C to 125°C. The dual LTC6081 is
available in 8-lead MSOP and 10-lead DFN10 packages.
The quad LTC6082 is available in 16-lead SSOP and DFN
packages.
