LT1011IS8#PBF

LT1011 is a general purpose comparator with significantly better input characteristics than the LM111. Although pin compatible with 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. It is several times faster than 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 device retains all 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. Applications include SAR A/D converters, voltage-to-frequency converters, precision RC oscillator, peak detector, motor speed control, pulse generator, relay/lamp driver.
