Cissoid comparator for extreme temperatures
Cissoid has introduced a high-speed comparator which it guarantees for operation from -55°C up to +225°C.
Dubbed Volga, it is available in a 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.
