Linear Technology LT1490A

The LT1490A operates on all single and split supplies with a total voltage of 2V to 44V, drawing only 40µA of quiescent current per amplifier. It is reverse supply protected; it draws virtually no current for reverse supply up to 18V. The input range of the LT1490A includes both supplies and the output swings to both supplies.

It is recommended for all new designs. Unlike most micropower op amps, the LT1490A can drive heavy loads; its rail-to-rail output drives 20mA.
