Product Description

Description:

The CJMCU-7705 TM7705 is a 2/3-channel analog front end for low frequency measurements. The device can accept a low level input signal directly from the sensor and then produce a serial digital output. The use of Σ-Δ conversion technology to achieve 16-bit loss of code performance. The selected input signal is sent to a programmable programmable front end based on the analog modulator. The on-chip digital filter handles the output signal of the modulator. The on-chip control register adjusts the cutoff point of the filter and the output update rate to program the first notch of the digital filter.
CJMCU-7705 TM7705 only need 2.7 ~ 3.3V or 4.75 ~ 5.25V single power supply. The TM7705 is a dual channel fully differential analog input with a differential reference input. When the supply voltage is 5V, the reference voltage is 2.5V, the device can be input signal range from 0 ~ +20 mV to 0 ~ +2.5 V signal processing. But also to deal with ± 20mV ~ ± 2.5V bipolar input signal for the TM7705 is AIN (-) input as a reference point. When the supply voltage is 3V and the reference voltage is 1.225V, it can handle 0 ~ + 10mV to 0 ~ + 1.225V
Unipolar input signal, its bipolar input signal range is ± 10mV to ± 1.225V. Therefore, TM7705 can achieve 2/3 channel system all the signal conditioning and conversion.
The CJMCU-7705 TM7705 is ideal for intelligent systems, microcontroller systems and DSP-based systems. The serial interface can be configured as a three-wire interface. The gain value, the polarity of the signal, and the selection of the update rate can be configured by software using the serial input port. The device also includes self-calibration and system calibration options to eliminate the gain and offset errors of the device itself or the system. CMOS architecture ensures extremely low power consumption, power-down mode reduces power consumption to 20μW (typical).
