The TS331, TS332 and TS334 are single, dual and quad micropower and low-voltage comparators. They can operate with a supply voltage ranging from 1.6 V to 5 V with a typical current consumption as low as 20 μA. In addition, rail-to-rail inputs make them a perfect choice for low-voltage applications. Their availability in tiny packages is a real advantage for overcoming space constraints. The TS33x are specified for temperatures between -40 °C to +125 °C, making them ideal for a wide range of applications.

The TS33 family of low power series voltage references is capable of providing stable and precise output voltages with an initial accuracy of 0.15% over an extended temperature range (-40 to +125 °C). The ultra low operating current is a key advantage for power-restricted designs. In addition, the TS33 is very stable over the entire operating temperature range, making it suitable for high-precision applications. Available in QFN8, SOT23-3L and SOT323-3L surface mount packages, the TS33 can be designed in applications where space saving is a critical issue.

The TS339 device is a micro-power, CMOS, quad voltage comparator with extremely low consumption of 9 μA typ./comparator (20 times less than the bipolar LM339). Similar performances are offered by the quad micro-power comparator TS3704 with a push-pull CMOS output. Thus response times remain similar to the LM339 device.

The TS3431 is an adjustable shunt voltage reference with guaranteed temperature stability over the entire operating temperature range (- 40 °C to + 125 °C). The output voltage can be set to any value between 1.24 V and 24 V with an external resistor bridge. Available in SOT23-3 surface mount package, it can be used in application designs where space saving is critical.

The TS3702 is a micropower CMOS dual voltage comparator with extremely low consumption of 9µA typ / comparator (20 times less than bipolar LM393). The push-pull CMOS output stage allows power and space saving by eliminating the external pull-up resistor required by usual open-collector output comparators. Thus response times remain similar to the LM393.

These devices consist of two independent precision voltage comparators, designed to operate with single or dual supplies. These differential comparators use the STMicroelectronics silicon lin MOS process giving them an excellent consumption-speed ratio. These devices are ideally suited for low consumption applications.
