LM193QML

LM193A, LM193QML www.ti.com SNOSAM2C – MAY 2005 – REVISED MARCH 2013 LM193A/LM193QML Low Power Low Offset Voltage Dual Comparators Check for Samples: LM193A, LM193QML FEATURES 1 2 Available with Radiation Guarantee – Total Ionizing Dose 100 krad(Si) – ELDRS Free 100 krad(Si) Wide Supply – Voltage Range: 2.0VDC to 36VDC – Single or Dual Supplies: ±1.0V to ±18V Very Low Supply Current Drain (0.4 mA) — Independent of Supply Voltage Low Input Biasing Current: 25 nA typ Low Input Offset Current: ±5 nA typ Input Common-Mode Voltage Range Includes Ground Differential Input Voltage Range Equal to the Power Supply Voltage Low Output Saturation Voltage,: 250 mV at 4 mA typ Output Voltage Compatible with TTL, DTL, ECL, MOS and CMOS Logic Systems DESCRIPTION The LM193 series consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0 mV max for two comparators which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage. Application areas include limit comparators, simple analog to digital converters; pulse, squarewave and time delay generators; wide range VCO; M...
