A high-temperature, high-speed, rail-to-rail comparator fits in TDFP package

June 12, 2012 // By Paul Buckley
CISSOID is launching VOLGA, the first high-speed comparator guaranteed for operation from -55°C up to +225°C.

VOLGA is a comparator available in a TDFP (thin dual flat pack) surface mount hermetically sealed ceramic package, with footprint of only 5 x 5.5 mm. The device requires a 5 V (±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. The device's output implements a push-pull CMOS stage, that can sink or source up to 16 mA. Typical propagation delay at 20 mV 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 device can be ordered now for sampling and evaluation under the part number CHT-RIV1675A.

Pricing starts at 159.08€/unit up to 200 units.
