HT93111/HT93121
Low Power Comparator
General Information
The HT93111/HT93121/HT93112/HT93122 family of low power comparators offers the benefits of low power consumption, low offset voltage and low offset drift. The HT93111/HT93121 are offered in single channel and the HT93112/HT93122 are offered in dual channel. They have low propagation delay and have good PSRR and CMRR characteristics. These devices also provide full rail-to-rail input and output operation.
The devices operate with a single supply voltage as low as 1.4V and with a low supply current of 0.8μA/comparator (Typ.).
The HT93111/HT93112 family of comparators has push-pull output and supports rail-to-rail output swing and interfaces with TTL/CMOS logic. However, the HT93121/HT93122 family of comparators has open-drain output and can be used as a level-shifter for up to 6V using a pull-up resistor.
With their single wide range of supply voltage and low power consumption features coupled with their low offset voltage, these comparators are suitable for use in a wide range of applications. Besides, small-sized packages provide options for portable and space-restricted applications.
