TS391A Description

Short technical summary and product information.

The TS391A from UTC is a low-power single voltage comparator that operates over a wide single supply voltage range from 2 V to 36 V, or from dual supplies of ±1 V to ±18 V. This comparator is designed for efficiency, consuming a very low supply current of 0.2 mA, independent of the supply voltage. It features low input bias current of 25 nA typical and low input offset current of ±5 nA typical. The input common-mode voltage range includes ground, even when using a single power supply.

Key electrical characteristics include a low input offset voltage of ±2 mV maximum for the TS391A variant, and a low output saturation voltage of 250 mV typical at 4 mA. The differential input voltage range is equal to the supply voltage, providing flexibility in design. The outputs are compatible with TTL, DTL, ECL, and CMOS logic families.

The TS391A is available in compact surface-mount packages, including the SOT-23-5 and DFN8 2x2. These packages are suitable for applications where space is a constraint. The device operates within a maximum junction temperature of 150 °C and has a storage temperature range of -65 °C to 150 °C.
