TDC-GP22中文资料Next generation time-to-digital converter with integrated analog front-end数据手册ams-OSRAM规格书

描述 Description

TDC-GP22 is a 2-channel TDC with additional analog elements like extended fire-pulse generator, zero-cross detection and analog switches for simplifying the use in ultrasonic flow meter applications. The addition first-hit detection makes TDC-GP22 suitable for high dynamic applications as ultrasonic water meters. An optimized power managements of the various units brings down the operating current to a few µA at 2Hz measuring rate.
