LT1011/LT1011A

Voltage Comparator

FEATURES

DESCRIPTIO

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

timeslowerbiascurrent,sixtimesloweroffsetvoltageand

five times higher voltage gain. Offset voltage drift, a

previously unspecified parameter, is guaranteed at

15µV/°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

withouttrimming. Ina12-bitA/Dapplication, forinstance,

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

isspecifiedupto50VbetweenV^–andthecollectoroutput.

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.
