LT6200 driven into clipping while connected in a gain of
AV = 1. In this photo, the input signal generator is clipping

ESD
The LT6200 has reverse-biased ESD protection diodes on
all inputs and outputs, as shown in Figure 1. If these pins
are forced beyond either supply, unlimited current will
flow through these diodes. If the current is transient and
limitedto30mAorless,nodamagetothedevicewilloccur.
Noise
The noise voltage of the LT6200 is equivalent to that of
a 56Ω resistor—and for the lowest possible noise, it is
desirable to keep the source and feedback resistance
at or below this value (i.e., RS + RG//RFB ≤ 56Ω). With
RS + RG//RFB = 56Ω the total noise of the amplifier is:
en = √(0.95nV)2 + (0.95nV)2 = 1.35nV. Below this resis-
tance value the amplifier dominates the noise, but in the
resistance region between 56Ω and approximately 6kΩ,
the noise is dominated by the resistor thermal noise. As
the total resistance is further increased, beyond 6k, the
noise current multiplied by the total resistance eventually
dominates the noise.
For a complete discussion of amplifier noise, see the
LT1028 data sheet.
Power Dissipation
The LT6200 combines high speed with large output cur-
rent in a small package, so there is a need to ensure that
the die’s junction temperature does not exceed 150°C.
The LT6200 is housed in a 6-lead TSOT-23 package. The
package has the Vsupply pin fused to the lead frame to
enhance the thermal conductance when connecting to a
ground plane or a large metal trace. Metal trace and plated
through-holescanbeusedtospreadtheheatgeneratedby
the device to the backside of the PC board. For example,
on a 3/32" FR-4 board with 2oz copper, a total of 270mm2
connects to Pin 2 of the LT6200 (in a TSOT-23 package)
bringing the thermal resistance,
θJA, to about 135°C/W.
Without an extra metal trace beside the power line con-
necting to the Vpin to provide a heat sink, the thermal
resistance will be around 200°C/W. More information on
thermal resistance with various metal areas connecting
to the Vpin is provided in Table 1.

Device is mounted on topside.
Junction temperature TJ is calculated from the ambient
temperature TA and power dissipation PD as follows:
TJ = TA + (PD θJA)
The power dissipation in the IC is the function of the sup-
ply voltage, output voltage and the load resistance. For
a given supply voltage, the worst-case power dissipation
PD(MAX) occurs at the maximum quiescent supply current
and at the output voltage which is half of either supply
voltage (or the maximum swing if it is less than half the
supply voltage). PD(MAX) is given by:
PD(MAX) = (VS IS(MAX)) + (VS/2)2/RL

area of PC board without any extra heat spreading plane
connected to its Vpin has a thermal resistance of
