dengral Description
Maxim's MXL1178 and MXL1179 are dual and quad
micropower, precision op amps. They feature an
extremely low 17pA max per op amp supply current, as
well as precision offset specifications: 30pV offset volt-
age, and SOpA offset current. Both offset parameters
have low drift over temperature and time.
The MXL1178 and MXL1179 can operate from a single
supply (e.g., one lithium cell or two NiCd cells). The
input voltage range includes ground. The output stage
swings to within a few millivolts of ground while sinking
current, which eliminates pull-down resistors and saves
power.
Both devices are optimized for +5V single-supply
operation, but specifications for t15V operation are
also provided.
Maxim's MXL1178 and MXL1179 are pin compatible
with industry standards such as the LT1178 and
LT1179. For applications that require smaller
packaging, see the MAX478/MAX479 data sheet. For
applications that require lower power, see the
MAX406/MAX407/MAX409 1pA op amp data sheet.
