Operational Amplifiers

 

End of Life (EOL) Notice »

 

Silicon Labs has the industry’s first sub-1 µA supply current, precision CMOS operational amplifiers fully specified to operate over a supply voltage range from 0.8 V to 5.5 V, and are optimized for ultra-long-life battery powered applications. The operational amplifiers exhibit a typical input bias current of 2 pA, and have rail-to-rail input and output stages.

The operational amplifiers combined features make them an excellent choice in applications where very low supply current and low operating supply voltage translate into very long equipment operating time. Applications include: micropower active filters, wireless remote sensors, battery and powerline current sensors, portable gas monitors, and handheld/portable POS terminals.

Silicon Labs operational amplifiers are fully specified over the industrial temperature range (-40 to +85°C) and are available in either a PCB-space saving 5-lead SC70 or a 5-lead SOT23 package.
