OPA336N/250单电源微功耗CMOS运算放大器可国产替代

　　OPA336 series microPower CMOS operational amplifiers are designed for battery-powered applications.They operate on a single supply with operation as low as 2.1V.The output is rail-to-rail and swings to within 3mV of the supplies with a 100k load.The common-mode range extends to the negative supply—ideal for single-supply applications.Single,dual,and quad versions have identical specifications for maximum design flexibility.

 

　　In addition to small size and low quiescent current(20µA/amplifier),they feature low offset voltage(125µV max),low input bias current(1pA),and high open-loop gain(115dB).Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction.

 

　　OPA336 packages are the tiny SOT23-5 surface mount and SO-8 surface-mount.OPA2336 comes in the miniature MSOP-8 surface-mount,SO-8 surface-mount,and DIP-8 packages.The OPA4336 packages is the space-saving SSOP-16 surface-mount.

 

　　All are specified from–40°C to+85°C and operate from–55°C to+125°C.A macromodel is available for download(at www.ti.com)for design analysis.
