ST Microelectronics has introduced a monolithic IC that includes two comparators and a shunt voltage reference. The TSM109 can offer space and cost savings in applications such as power supplies and data acquisition.
The comparators in the TSM109 work from a supply voltage of ±1 V to ±18 V and have ESD protection up to 1,5 kV. The comparators draw a supply current of 1,1 mA, independent of the supply voltage, and need an input bias current of 25 nA (typ). The input offset voltage is ±1 mV (typ). The input common-mode voltage range includes ground.
The output saturation voltage is 250 mV (typ), at an I/O of 4 mA and the differential input voltage range is equal to the supply voltage. The voltage reference offers a fixed Vref of 2,5 V, with 0,4% and 1% voltage precision and will sink between 1 mA and 100 mA of current.
The parts are available in an 8-pin plastic DIP or an SO8 package.
