It is designed to operate over a wide range of supply voltages, with a minimum supply voltage of 2.7V. The common mode voltage range of the LMC6772 exceeds both the positive and negative supply rails, a significant advantage in single supply applications. The open drain output of the LMC6772 allows for wired-OR configurations. The open drain output also offers the advantage of allowing the output to be pulled to any voltage rail up to 15V, regardless of the supply voltage of the LMC6772. The LMC6772 is targeted for systems where low power consumption is the critical parameter. Ensured operation at supply voltages of 2.7V and rail-to-rail performance makes this comparator ideal for batterypowered applications. Refer to the LMC6762 datasheet for a push-pull output stage version of this device.

Copyright © 1995–2013, Texas Instruments Incorporated LMC6772 SNOS749F – SEPTEMBER 1995 – REVISED MARCH 2013 www.ti.com These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.

Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not ensured. For ensured specifications and the test conditions, see the electrical characteristics. (2) Human body model, 1.5 kΩ in series with 100 pF. The output pins of the two comparators (pin 1 and pin 7) have an ESD tolerance of 1.5 kV. All other pins have an ESD tolerance of 2 kV. (3) Limiting input pin current is only necessary for input voltages that exceed absolute maximum input voltage ratings. (4) Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of 150°C. Output currents in excess of ±30 mA over long term may adversely affect reliability. (5) Do not short circuit output to V+, when V+ is > 12V or reliability will be adversely affected. (6) The maximum power dissipation is a function of TJ(MAX), θJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX) – TA)/θJA. All numbers apply for packages soldered directly into a PC board.
