DESCRIPTION

The TSM931–TSM934 family of single/dual/quad, low-voltage, micropower analog comparators is electrically and form-factor identical to the MAX931-MAX934 family of analog comparators. Ideal for 3V or 5V single-supply applications, the TSM931–TSM934 family can operate from single +2.5V to +11V supplies or from ±1.25V to ±5V dual supplies. The single TSM931 draws less than 4μA (max) supply current over temperature. The dual TSM932/TSM933 and the quad TSM934 each 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. In addition, the comparators’ push-pull output stages are TTL/CMOS compatible and capable of sinking and sourcing current. The TSM931/TSM932/TSM933 each incorporates an internal 1.182V ±2% voltage reference. Without complicated feedback configurations and only requiring two additional resistors, adding external hysteresis via a separate pin is available on the TSM931, the TSM932, and the TSM933.
