DESCRIPTION

The LTC®6084/LTC6085 are dual/quad, low cost, low offset, rail-to-rail input/output, unity-gain stable CMOS operational amplifi ers that feature 1pA of input bias current.

A 1.5MHz gain bandwidth, and 0.5V/μs slew rate, along with the wide supply range and a low 0.75mV offset, make the LTC6084/LTC6085 useful in an extensive variety of applications from data acquisition to medical equipment and consumer electronics. The 110μA supply current and the shutdown mode are ideal for signal processing applications which demand performance with minimal power.
