LT1638/LT1639
1.2MHz, 0.4V/µs
Over-The-Top Micropower
Rail-to-Rail Input and Output
Op Amps
DESCRIPTION
The LT
®
1638 is a low p wer 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 in the standard 14-pin PDIP
and surface mount packages. For space limited applications
the LT1638 is available in a 3mm x 3mm x 0.8mm dual
fine pitch leadless package (DFN).
The LT1638/LT1639 op amps operate on all single and split
supplies with a total voltage of 2.5V to 44V drawing only
170μA of quiescent current per amplifier. These ampli-
fiers are reverse battery protected and draw no current
for reverse supply up to 18V.
The input range of the LT1638/LT1639 includes both sup-
plies, 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 when the inputs are 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.
