TM7707

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. TM7707 Is dual channel fully differential Analog input, while TM7708 Yes 3 Channel pseudo differential analog input, both have a differential reference input. When the power supply voltage is 5V , The reference voltage is 2.5V When these two devices can change the input signal range from 0~+20mV To 0~+2.5V The signal is processed. Can also handle ±20mV~±2.5V Bipolar input signal, for TM7707 So AIN (-) The input terminal is the reference point, and TM7708 Yes COMMON Input terminal. When the power supply voltage is 3V , The reference voltage is 1.225V Can be processed 0~+10mV To 0~+1.225V Unipolar input signal, its bipolar input signal range is ±10mV To ±1.225V . therefore, TM7707/8 can be realised 2/3 The conditioning and ...
