The TSX393 is a micropower CMOS dual voltage comparator which exhibits a very low current consumption of 5 µA typical per comparator. This device was designed as the improvement of the TS393: it shows a lower current consumption, a better input offset voltage, and an enhanced ESD tolerance. The TSX393 is fully specified over a wide temperature range and is proposed in automotive grade for the SO8 package. It is fully compatible with the TS393 CMOS comparator and is available with similar packages. New tiny packages (MiniSO8 and DFN8 2x2 mm) are also proposed for the TSX393 thus allowing even more integration on applications.
Key Features
- Low supply current: 5 µA typ. per comparator
- Wide single supply range 2.7 V to 16 V or dual supplies (±1.35 V to ±8 V)
- Extremely low input bias current: 1 pA typ.
- Input common-mode voltage range includes ground
- Open drain output
- High input impedance: 1012 Ω typ
- Fast response time: 2 µs typ. for 5 mV overdrive
- ESD tolerance: 4 kV HBM, 200 V MM
