General Description
The TC1040 is a mixed-function device combining two
comparators and a voltage reference in a single 8-pin
package. The inverting input of Comparator A and the
non-inverting input of Comparator B are internally
connected to the reference.
This increased integration allows the user to replace
two packages, which saves space, lowers supply
current and increases system performance. The
TC1040 operates from two 1.5V alkaline cells down to
V
DD
= 1.8V. It requires only 10
μ
A typical of supply
current, which significantly extends battery life. A low
power shutdown input (SHDN) disables one of the
comparators, placing its outputs in a high-impedance
state. This mode saves battery power and allows
comparator outputs to share common analog lines
(multiplexing). Shutdown current is 6
μ
A (typical).
Rail-to-rail inputs and outputs allow operation from low
supply voltages with large input and output signal
swings.
Packaged in an 8-Pin MSOP, the TC1040 is ideal for
applications requiring low power level detection.
