LT1011/LT1011A
Voltage Comparator
The LT
1011 is a general purpose comparator with sig-
nificantly better input characteristics than the LM111.
Although pin compatible with the LM111, it offers four
times lower bias current, six times lower offset voltage and
five times higher voltage gain. Offset voltage drift, a
previously unspecified parameter, is guaranteed at
15
μ
V/
°
C. Additionally, the supply current is lower by a
factor of two with no loss in speed. The LT1011 is several
times faster than the LM111 when subjected to large
overdrive conditions. It is also fully specified for DC
parameters and response time when operating on a single
5V supply. These parametric improvements allow the
LT1011 to be used in high accuracy (
≥
12-bit) systems
without trimming. In a 12-bit A/D application, for instance,
using a 2mA DAC, the offset error introduced by the
LT1011 is less than 0.5LSB. The LT1011 retains all the
versatile features of the LM111, including single 3V to
±
18V supply operation, and a floating transistor output
with 50mA source/sink capability. It can drive loads refer-
enced to ground, negative supply or positive supply, and
is specified up to 50V between V
–
and the collector output.
A differential input voltage up to the full supply voltage is
allowed, even with
±
18V supplies, enabling the inputs to
be clamped to the supplies with simple diode clamps.
