TDC-GP30YD数据手册集成电路（IC）的传感器检测器接口规格书PDF

描述 Description

Its performance with respect to resolution and temperature stability (offset drift) is proven in millions of installations. It drastically simplifies the design of ultrasonic heat and water meters and is the solution with the lowest power consumption at higher sample rates including the flow calculation (8.5µA at 8 Hz sample rate). It manages the complete ultrasonic process, driving the piezos, capturing the received bursts with an offset-stabilized zero-crossing detector, amplitude monitoring, first-hit level detection.

The integrated CPU allows to do averaging, filtering or even the complete flow calculation.

TDC-GP30 is offered in two package variants, QFN32 (YD) and QFN40 (YA) for application of an external amplifier.

TDC-GP30Yx-F01 comes with a flow firmware already on chip, which simplifies the design of ultrasonic water meters and reduces time to market. It covers the whole ultrasonic measurement task so that users have the full flexibility in the choice of the meters central processor and can continue with their existing platforms and software libraries.

特性 Features

• High performance and ultra-low power 32-Bit CPU with 4k NVRAM and 4k ROM

• Up to 31 multi-hits for flow measurement yield the highest accuracy

• Advanced high-precision analog part

• Transducers can be connected directly to GP30, no external components required

• Amplitude measurements of receiving signal for secure bubble, aging and empty spool piece detection

• High update rates with very low power consumption (e.g. 6 µA@8Hz)
