n Guaranteed Max 0.5mV Input Offset Voltage
n Guaranteed Max 25nA Input Bias Current
n Guaranteed Max 3nA Input Offset Current
n Guaranteed Max 250ns Response Time
n Guaranteed Min 200,000 Voltage Gai 50mA Output Current Source or Sink
n ±30V Differential Input Voltage
n Fully Specified for Single 5V Operatio Available in 8-Lead PDIP and SO Packages The LT®1011 is a general purpose comparator with significantly 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
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. 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 referenced to ground, negative supply or positive supply, and is specified up to 50V …
