The LT1011 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 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.
