MTA8521可替代HTC8521
The MTA8521 (single) and MTA8522 (dual) are
ultra-low power operational amplifiers that
provide 140kHz bandwidth with only 4μA
quiescent current. These rail-to-rail input and
output amplifiers are specifically designed for
battery-powered applications. The input
common-mode voltage range extends 300mV
beyond the power supply rails and the output
swings to only 10mV of the rails, maintaining
wide dynamic range. Unlike some micro-power
op-amps, these parts are unity-gain stable. The
MTA852x family features a low input bias
current that allows the use of large source and
feedback resistors.
The MTA852x op-amps are specified for single
or dual power supplies of +1.8V to +5.5V. All
models are specified over the extended
industrial temperature range of −40°C to +85°C.
The MTA8521 is available in SC70-5 and
SOT23-5 packages. The MTA8522 is available
in MSOP-8、SOIC-8 and TSSOP-8 packages.
