Low power dual voltage comparator
Product specification
LM193/A/293/A/393/A/2903
DESCRIPTION
The LM193 series consists of two independent precision voltage
comparators with an offset voltage specification as low as 2.0mV
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.
The LM193 series was designed to directly interface with TTL and
CMOS. When operated from both plus and minus power supplies,
the LM193 series will directly interface with MOS logic where their
low power drain is a distinct advantage over standard comparators.
FEATURES
• Wide single supply voltage range 2.0VDC to 36VDC or dual
supplies ±1.0VDC, to ±18VDC
• Very low supply current drain (0.8mA) independent of supply
voltage (2.0mW/comparator at 5.0VDC)
• Low input biasing current 25nA
• Low input offset current ±5nA and offset voltage ±2mV
• Input common-mode voltage range includes ground
• Differential input voltage range equal to the power supply voltage
• Low output 250mV at 4mA saturation voltage
• Output voltage compatible with TTL, DTL, ECL, MOS and CMOS
logic systems
APPLICATIONS
• A/D converters
• Wide range VCO
• MOS clock generator
• High voltage logic gate
• Multivibrators
