FEATURES  
DESCRIPTION  
The LT®1638 is a low power dual rail-to-rail input and output  
operationalamplifieravailableinthestandard8-pinPDIPand  
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.  
Operates with Inputs Above V+

Gain Bandwidth Product: 1.2MHz  
Slew Rate: 0.4V/µs  
High Output Current: 25mA Min  
Specified on 3V, 5V and ±15V Supplies  
Reverse Battery Protection to 18V  
No Supply Sequencing Problems  
High Voltage Gain: 1500V/mV  
Single Supply Input Range: –0.4V to 44V  
High CMRR: 98dB  
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  
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,andauniquefeatureofthisdeviceisitscapability  
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  
falseoutputsfromoccurringevenwhentheinputsare22V  
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  
negativesupply.TheLT1638/LT1639candriveloadsupto  
25mAandstillmaintainrail-to-railcapability.Theopamps  
are unity-gain stable and drive all capacitive loads up to  
1000pF when optional output compensation is used.
