FEATURES

DESCRIPTION

TheLT^®1495/LT1496arethelowestpower(I_S≤ 1.5µA)op

amps with precision specifications. The extremely low

supply current is combined with excellent amplifier speci-

fications: input offset voltage is 375µV maximum with a

typical drift of only 0.4µV/°C, input offset current is 100pA

maximum.Aminimumopen-loopgain(A_VOL)of100V/mV

ensures that gain errors are small. The device character-

istics change little over the supply range of 2.2V to ±15V.

Supply rejection is 90dB and the common mode rejection

ratio is 90dB. Operation is specified for 3V, 5V and ±15V

supplies. Reverse battery protection (–18V min) and

inputs that operate above the positive supply make the

LT1495/LT1496 easy to use in harsh environments.

ply applications with ground referred loads and feedback

networks,nootherprecautionsarerequired.Ifthereverse

battery condition results in a negative voltage at either the

input pins or output pin, the current into the pin should be

limited by an external resistor to less than 10mA.

Micropower op amps are sometimes not micropower

during start-up, wreaking havoc on low current supplies.

Intheworstcase,theremaynotbeenoughsupplycurrent

availabletotakethesystemuptonominalvoltages.Figure

1 is a graph of LT1495 supply current vs supply voltage

for the three limit cases of input offset that could occur

during start-up. The circuits are shown in Figure 2. One

circuitcreatesapositiveoffset,forcingtheoutputtocome

up saturated high. Another circuit creates a negative

offset, forcing the output to come up saturated low, while

thelastbringsuptheoutputathalfsupply.Inallcases,the

supply current is well behaved. Supply current is highest

with the output forced high, so if one amplifier is unused,

it is best to force the output low or at half supply.

Inputs

While the LT1495/LT1496 will function normally with its

inputstakenabovethepositivesupply,thecommonmode

range does not extend beyond approximately 300mV be-

low the negative supply at room temperature. The device

will not be damaged if the inputs are taken lower than

300mV below the negative supply as long as the current

out of the pin is limited to less than 10mA. However, the

outputphaseisnotguaranteedandthesupplycurrentwill

increase.

OUTPUT LOW

Thegraph,CapacitiveLoadHandling,showsamplifiersta-

to be operated within about 100mV of the positive rail, the

allowable load capacitance is less. With this output volt-

age, theworstcaseoccursatA_V=1andlightloads, where

the load capacitance should be less than 500pF with a 5V

supply and less than 100pF with a 30V supply.

Rail-to-Rail Operation

The simplified schematic, Figure 3, details the circuit

design approach of the LT1495/LT1496. The amplifier

topology is a three-stage design consisting of a rail-to-rail

input stage, that continues to operate with the inputs

above the positive rail, a folded cascode second stage that

develops most of the voltage gain, and a rail-to-rail com-

mon emitter stage that provides the current gain.

TheinputstageisformedbytwodiffampsQ1-Q2andQ3-

Q6.ForsignalswithacommonmodevoltagebetweenV_EE

and (V_CC– 0.8V), Q1 and Q2 are active. When the input

common mode exceeds (V_CC– 0.8V), Q7 turns on,

diverting the current from diff amp Q1-Q2 to current

mirrorQ8-Q9.ThecurrentfromQ8biasesontheotherdiff

ampconsistingofPNP’sQ5-Q6andNPN’sQ3-Q4.Though

Q5-Q6 are driven from the emitters rather than the base,

the basic diff amp action is the same. When the common

modevoltageisbetween(V_CC–0.8V)andV_CC,devicesQ3

and Q4 act as followers, forming a buffer between the

amplifier inputs and the emitters of the Q5-Q6. If the

common mode voltage is taken above V_CC, Schottky

diodesD1andD2reversebiasanddevicesQ3andQ4then

act as diodes. The diff amp formed by Q5-Q6 operates

normally, however, the input bias current increases to the

emitter current of Q5-Q6, which is typically 180nA. The

graph, Input Bias Current vs Common Mode Voltage

found in the Typical Performance Characteristics section,

shows these transitions at three temperatures.

The collector currents of the two-input pairs are combined

in the second stage consisting of Q11 to Q16, which

furnishes most of the voltage gain. Capacitor C1 sets the

amplifier bandwidth. The output stage is configured for

maximum swing by the use of common emitter output

devices Q21 and Q22. Diodes D4 to D6 and current source

Q15 set the output quiescent current.
