LM111JAN Voltage Comparator
Check for Samples: LM111JAN
•2 Operates from Single 5V Supply
• Input Current: 200 nA max. Over Temperature
• Offset Current: 20 nA max. Over Temperature
• Differential Input Voltage Range: ±30V
• Power Consumption: 135 mW at ±15V
• Power Supply Voltage, single 5V to ±15V
• Offset Voltage Null Capability
• Strobe Capability
The LM111 is a voltage comparator that has input
currents nearly a thousand times lower than devices
such as the LM106 or LM710. It is also designed to
operate over a wider range of supply voltages: from
standard ±15V op amp supplies down to the single
5V supply used for IC logic. The output is compatible
with RTL, DTL and TTL as well as MOS circuits.
Further, it can drive lamps or relays, switching
voltages up to 50V at currents as high as 50 mA.
Both the inputs and the outputs of the LM111 can be
isolated from system ground, and the output can
drive loads referred to ground, the positive supply or
the negative supply. Offset balancing and strobe
capability are provided and outputs can be wire
OR'ed. Although slower than the LM106 and LM710
(200 ns response time vs 40 ns) the device is also
much less prone to spurious oscillations. The LM111
has the same pin configuration as the LM106 and
Note: Pin 4 connected to case
