AD7746 - 24-Bit Capacitance-to-Digital Converter

Download the AD7746 datasheet PDF. This datasheet also covers the AD7745 variant, as both devices belong to the same 24-bit capacitance-to-digital converter family and are provided as variant models within a single manufacturer datasheet.

Description

The AD7745/AD7746 are a high resolution, Σ-Δ capacitance-todigital converter (CDC).

The capacitance to be measured is connected directly to the device inputs.

Features

  • Capacitance-to-digital converter New standard in single chip solutions Interfaces to single or differential floating sensors Resolution down to 4 aF (that is, up to 21 ENOB) Accuracy: 4 fF Linearity: 0.01% Common-mode (not changing) capacitance up to 17 pF Full-scale (changing) capacitance range: ±4 pF Tolerant of parasitic capacitance to ground up to 60 pF Update rate: 10 Hz to 90 Hz Simultaneous 50 Hz and 60 Hz rejection at 16 Hz Temperature sensor on-chip Resolution: 0.1°C, accuracy: ±2°C Vol.
