CISSOID launches VOLGA, a high-temperature, high-speed, rail-to-rail comparator in a tiny TDFP package

CISSOID, the leader in high-temperature semiconductor solutions, launches 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 detector & 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.

The CHT-VOLGA datasheet is available now from CISSOID’s website (datasheet link). It can be ordered now for sampling and evaluation under the part number CHT-RIV1675A. Pricing starts at 159.08€/unit up to 200 units. For more information, visit or contact the company’s representatives at
