DUESCRIPTIO

The RH1078M is a micropower dual op amp in the
standard 8-pin configuration. This device is optimized for
single supply operation at 5V. Specifications for ±15V are
also provided.

The wafer lots are processed to LTC’s in-house Class S
flow to yield circuits usable in stringent military applica­tions.

Note 1: All noise parameters are for VS = ±2.5V, VO = 0V.
Note 2: This parameter is guaranteed by design, characterization or

correlation to other tested parameters.

Note 3: Power supply rejection ratio is measured at the minimum supply
voltage. The op amps actually work at 1.8V supply but with a typical offset
skew of –300µV.
