Optimized for 3V and 5V power supplies, they operate over a single supply voltage range from 2.4V to 12V or from ±2.4V to ±6V dual supplies. The LT1711/LT1712 are designed for ease of use in a variety of systems. In addition to wide supply voltage flexibility, rail-to-rail input common mode range extends 100mV beyond both supply rails, and the outputs are protected against phase reversal for inputs extending further beyond the rails. Also, the rail-to-rail inputs may be taken to opposite rails with no significant increase in input current. The rail-to-rail matched complementary outputs interface dire...
