The LT ®1011 is a general purpose parator with significantly better input characteristics than the LM111. Although pin patible 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. 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 2m A 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 50m A source/sink capability. It can drive loads referenced to ground, negative supply or positive supply, and is specified up to 50V between V
