TDC-GP21 - Time-to-Dial Converter with integrated og Frontend

TDC-GP21 is next generation‘s upgrade for TDC-GP2. It offers pin-to-pin and functional compatibility, several feature improvements and an extended functionality. og elements like a chopper stabilized comparator and og switches simplify external circuits of ultrasonic flow meters in a significant manner. In parallel, measurement quality is improved and operating current is reduced. The fire pulse generator is extended, a new low-power 32 kHz oscillator driver is implemented and the temperature measuring unit is further improved. All in all, the TDC-GP21 is ly suited to design ultra-compact and low-cost ultrasonic flow meters and heat meters.
