DESCRIPTION
The
TSM971/972/973/982/984
family
of
single/dual/quad, low-voltage, micropower analog
comparators is electrically and form-factor identical to
the MAX971/972/973/982/984 family of analog
comparators. Ideal for 3V or 5V single-supply
applications, this comparator family can operate from
single +2.5V to +11V supplies or from ±1.25V to
±5.5V dual supplies. The single TSM971 and the dual
TSM972 draw less than 4μA (max) supply current
over temperature. The TSM973/TSM982 duals and
the quad TSM984 draw less than 3μA per comparator
over temperature.
All comparators in this family exhibit an input voltage
range from the negative supply rail to within 1.3V of
the positive supply. Wired-OR applications are
enabled as the comparators’ output stages are open-
drain. A 1.182V reference is internal to the
TSM971/TSM973 (±1%) and the TSM982/TSM984
(±2%). Without complicated feedback configurations
and only requiring two additional resistors, adding
external hysteresis is available on the TSM971,
TSM973, and the TSM982.
