Rail-to-Rail Output
The output stage of the LTC6087/LTC6088 swings within
30mV of the supply rails when driving high impedance
loads, in other words when no DC load current is present.
See the Typical Performance Characteristics for curves of
output swing versus load current. The class AB design of
the output stage enables the op amp to supply load cur-
rents which are much greater than the quiescent supply
current. For example, the room temperature short circuit
current is typically 45mA.
Capacitive Load
LTC6087/LTC6088candrivecapacitiveloadupto100pFin
unity gain. The capacitive load driving capability increases
as the amplifier is used in higher gain configurations. A
small series resistance between the output and the load
further increases the amount of capacitance the amplifier
can drive.
SHDN Pins
Pins 5 and 6 are used for power shutdown when the
LTC6087 is in the DD package. If they are floating, internal
current sources pull Pins 5 and 6 to V+ and the amplifiers
operate normally. In shutdown the amplifier output is
high impedance and each amplifier draws less than 5A
current. This feature allows the part to be used in muxed
output applications as shown in Figure 3.
ESD
TheLTC6087/LTC6088hasreverse-biasedESDprotection
diodes on all inputs and outputs as shown in the Simplified
Schematic. If these pins are forced beyond either supply,
unlimited current will flow through these diodes. If the
current is transient and limited to one hundred milliamps
or less, no damage to the device will occur.
The amplifier input bias current is the leakage current of
these ESD diodes. This leakage is a function of the tem-
perature and common mode voltage of the amplifier, as
shown in the Typical Performance Characteristics.
Noise
Inthefrequencyregionabove1kHz,theLTC6087/LTC6088
shows good noise voltage performance. In this region,
noise can be dominated by the total source resistance of
the particular application. Specifically, these amplifiers
exhibit the noise of a 10k resistor, meaning it is desirable
to keep the source and feedback resistance at or below
this value, i.e., RS + RG||RFB ≤ 10k. Above this total source
impedance, the noise voltage is dominated by the resistor.
At low frequency, noise current can be estimated from the
expression in = √2qIB, where q = 1.6 10–19 coulombs.
Equating √4kTRΔf and R√2qIBΔf shows that for source
resistor below 50G
Ω the amplifier noise is dominated by
the source resistance. Noise current rises with frequency.
See the curve Noise Current vs Frequency in the Typical
Performance Characteristics section.
