24 bit Analog to digital converter TM7707/8
I. Overview
TM7707/8 Is used for low frequency measurement 2/3 The analog front end of the channel. The device can accept low-level input signals directly from the sensor, and then generate a serial digital output. use Σ-Δ Conversion technology Technique achieved twenty four No missing code performance. The selected input signal is sent to an analog modulator based Dedicated front end with programmable gain. The on-chip digital filter processes the output signal of the modulator. Send via on-chip control The register can adjust the cut-off point of the filter and the output update rate, thereby entering the first notch of the digital filter Line programming.
TM7707/8 Just 2.7~3.3V or 4.75~5.25V Single power supply.
