DESCRIPTIO

The LT
1638 is a low power dual rail-to-rail input and output
operational amplifier available in the standard 8-pin PDIP and
SO packages as well as the 8-lead MSOP package. The
LT1639 is a low power quad rail-to-rail input and output
operational amplifier offered on the standard 14-pin PDIP
and surface mount packages.
The LT1638/LT1639 op amps operate on all single and
split supplies with a total voltage of 2.5V to 44V drawing
only 170
μ
A of quiescent current per amplifier. These
amplifiers are reverse battery protected and draw no
current for reverse supply up to 18V.
The input range of the LT1638/LT1639 includes both
supplies, and a unique feature of this device is its capability
to operate over the top with either or both of its inputs
above V
+
. The inputs handle 44V, both differential and
common mode, independent of supply voltage. The input
stage incorporates phase reversal protection to prevent
false outputs from occurring even when the inputs are 22V
below the negative supply. Protective resistors are
included in the input leads so that current does not
become excessive when the inputs are forced below the
negative supply. The LT1638/LT1639 can drive loads up to
25mA and still maintain rail-to-rail capability. The op amps
are unity-gain stable and drive all capacitive loads up to
1000pF when optional output compensation is used.
