LM111JAN
www.ti.com SNOSAM9B – JULY 2008 – REVISED MARCH 2013 LM111JAN Voltage Comparator
Check for Samples: LM111JAN FEATURES DESCRIPTION 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 В±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. 1 2 Operates from Single 5V Supply
Input Current: 200 nA max. Over Temperature
Offset Current: 20 nA max. Over Temperature
Differential Input Voltage Range: В±30V
Power Consumption: 135 mW at В±15V
Power Supply Voltage, single 5V to В±15V
Offset Voltage Null Capability
Strobe Capability 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 …
