APPLICATIO S I FOR ATIO
LT1006
In automated production testing the output is forced to
1.4V by the test loop; offset voltage is measured with a
common mode voltage of zero and the negative supply at
zero (Pin 4). Without the test loop, these exact conditions
cannot be achieved. The test circuit shown ensures that
the output will never saturate even with worst-case offset
voltages (– 250µV over the – 55°C to 125°C range). The
effective common mode input is 0.3V with respect to the
negative supply. As indicated by the common mode rejec-
tion specifications the difference is only a few microvolts
between the two methods of offset voltage measurement.

Low Supply Operation
The minimum guaranteed supply voltage for proper
operation of the LT1006 is 2.7V. Typical supply current at
this voltage is 320µA; therefore, power dissipation is only
860µW.
Noise Testing
For application information on noise testing and
calculations, please see the LT1007 or LT1028 data sheet.
Supply Current Programming
Connecting an optional external resistor to Pin 8 changes
the biasing of the LT1006 in order to increase its speed or
to decrease its power consumption. If a higher slew rate is
required, connect the external resistor for Pin 8 to Pin 4
[see performance curves for Increasing Slew Rate
(R
current into Pin 8 (which is approximately 60mV above
V
This can be accomplished by connecting R
positive supply, or to save additional power, by obtaining
the injected current from a low voltage battery.
Comparator Applications
The single supply operation of the LT1006 and its ability to
swing close to ground while sinking current lends itself
to use as a precision comparator with TTL compatible
output.
