The LT

6015/LT6016/LT6017 are single/dual/quad rail-to-

rail input operational amplifiers with input offset voltage

trimmed to less than 50µV. These amplifiers operate on

single and split supplies with a total voltage of 3V to 50V

and draw only 315µA per amplifier. They are reverse

battery protected, drawing very little current for reverse

supplies up

to 50V.

The Over-The-Top

input stage of the LT6015/LT6016/

LT6017 is designed to provide added protection in tough

environments. The input common mode range extends

from V

–

to V

and beyond: these amplifiers operate with

inputs up to 76V above V

–

independent of V

. Internal

resistors protect the inputs against transient faults up

to 25V below the negative supply. The LT6015/LT6016/

LT6017 can drive loads up to 25mA and are unity-gain

stable with capacitive loads as large as 200pF. Optional

external compensation can be added to extend the capaci

tive drive capability beyond 200pF.

The LT6015 is offered in a 5-lead SOT package. The LT6016

dual op amp is available in an 8-lead MSOP package. The

LT6017 is offered in a 22-pin leadless DFN package.

LT6015/LT6016/LT6017 Applications Information Supply Voltage Inputs The positive supply pin of the LT6015/LT6016/LT6017 should be bypassed with a small capacitor (typically 0.1μF) as close to the supply pins as possible. When driving heavy loads an additional 4.7μF electrolytic capacitor should be added. When using split supplies, the same is true for the V– supply pin.
PAGE 14
LT6015/LT6016/LT6017 Applications Information The inputs are protected against temporary excursions to as much as 25V below V– by internal 1k resistor in series with each input and a diode from the input to the negative supply. Adding additional external series resistance will extend the protection beyond 25V below V–. The input stage of the LT6015/LT6016/LT6017 incorporates phase reversal protection to prevent the output from phase reversing for inputs below V–.

LT6015/LT6016/LT6017 Applications Information to 0V differential by feedback action of the amplifier. However, depending on the configuration of the feedback around the amplifier, this input resistance can boost noise gain, lower overall amplifier loop gain and closed loop bandwidth, raise output noise, with one benevolent effect in increasing amplifier stability. In the normal mode of operation (where V– < VCM < V+ –1.

LT6015/LT6016/LT6017 Applications Information Distortion In general, the die junction temperature (TJ) can be estimated from the ambient temperature TA, and the device power dissipation PD: There are two main contributors of distortion in op amps: output crossover distortion as the output transitions from sourcing to sinking current and distortion caused by nonlinear common mode rejection. If the op amp is operating in an inverting configuration there is no common mode induced distortion.
