The TC1037/TC1038/TC1039 are single, low-power
comparators designed for low-power applications.
These comparators are specifically designed for
operation from a single supply. However, operation
from dual supplies also is possible, and power supply
current is independent of the magnitude of the power
supply voltage. The TC1037/TC1038/TC1039 operate
fromtwo 1.5V alkaline cells down to VDD = 1.8V. Active
supply current is 4μA for the TC1037/TC1038 and 6μA
for the TC1039. Input and output swing of these
devices is rail-to-rail.
An active low shutdown input, SHDN, is available on
the TC1038 and disables the comparator, placing its
output in a high-impedance state. The TC1038 draws
only 0.05μA (typical) when the shutdown mode is
active.
An internally biased 1.20V bandgap reference is
included in the TC1039. The reference is accurate to
2.0 percent tolerance. This reference is independent of
the comparator in the TC1039.
Packaged in a 5-Pin SOT-23A (TC1037) or 6-Pin
SOT-23A (TC1038/TC1039), these single comparators
are ideal for applications requiring high integration,
small size and low power.
