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 ±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 via a separate pin is available on the TSM971, the TSM973, and the TSM982.
