DESCRIPTIO
ABSOLUTE
AXI U
RATI GS
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 applica-
tions.

Note 1:
All noise parameters are for V
S
=
±2.5V,
V
O
= 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.
