GXSC GX7683 (Replace AD7683) to help PCR Instrument

In the PCR instrument, in order to carry out constant temperature control, often used to temperature sensors for temperature sampling, in the temperature sampling part, usually using the NTC plus op-amps and ADCs to detect the form of the following to introduce you to an ADC GX7683. GX7683 has the following characteristics:

1, GX7683 is a 16-bit sampling analog-to-digital (A/D) converter in the 2.7V to 5.25V power supply range with reliable specifications.

2, GX7683 even in the 100kHz data rate operation, only a very small amount of power; in the 10kHz data rate, the average power consumption is less than 100mw; in the lower data rate, the device‘s high speed allows it to spend most of the time in the power-down mode, greatly reducing the current consumption during idle.

3、Adopting l²C interface to communicate with the main control MCU, which is convenient and concise.

4、Accuracy is up to 16 bits, which can meet the accuracy requirements of most scenarios.

5, GX7683 has operation from 2V to 5.25V, synchronous serial (SPI/SSI compatible) interface and differential input.

6, The reference voltage can be set to any level within the range of 500mV to VCC.

7, ultra-low power and small size makes the GX7683 ideal for portable and battery-operated systems. the GX7683 is packaged in an 8-pin VSSOP package, saving PCB board area.

8, can replace the AD7683 of ADI (ADI).
