CISSOID has launched VOLGA, the first high-speed comparator guaranteed for operation from -55°C up to +225°C.
VOLGA is a comparator available in a tiny TDFP (thin dual flat pack) surface mount, hermetically-sealed ceramic package, with footprint of only 5 x 5.5mm. It requires a 5V (±10%) power supply and offers rail-to-rail input/output capability, as well as a shutdown mode that places the device in a low power consumption mode when the comparator function is not needed. The comparator features internal hysteresis for improved noise immunity. Its output implements a push-pull CMOS stage, that can sink or source up to 16mA. Typical propagation delay at 20mV overdrive is less than 30ns and has a low variation with temperature up to +225°C.
Applications include window comparators, threshold detectors and discriminators, zero-crossing detectors, clock regeneration, sensing and control. Compared to operational amplifiers implementation, the comparator VOLGA decreases cost and PCB area, with fewer passive components, higher speed and improved stability.
