Replacement AD7606, GX7606 ADC for Industrial Oil Valve Monitoring and Control

Industrial oil valve monitoring system usually consists of three major modules such as digital processing, multiplexed analog receiver, and oil valve sensor. In oil valve monitoring applications, its multiplexed analog receiving end is the process of sampling and quantization, the performance parameters of the ADC directly affect the accuracy and reliability of monitoring.

Resolution determines the minimum amount of analog signal changes that can be resolved, the higher the resolution, the stronger the ability to detect small signal changes. Conversion speed determines the frequency range of the analog signal that the ADC can process, for the monitoring of oil valve parameters with fast dynamic changes, a higher conversion speed is required.

The program uses the GXSC eight-channel 16-bit, sampling rate of 200kSPS ADC, because it is the GXSC ADC, so that the program design cost is low, and the data acquisition system is adaptable.

GX7606 for the 16-bit synchronous sampling chip, each chip has eight acquisition channels, can fully meet the requirements of the system on the sampling, it has a flexible digital filter, 2.5V reference voltage source, and high-speed parallel and serial interfaces, using a single 5V power supply, no longer need to positive and negative power supply and support for true bipolar signal input.

Performance parameters: 

1, each channel has a built-in analog input clamping protection, analog filter, programmable gain amplifier 

2, with 1MQ analog input impedance of the input buffer 

3, the operating temperature range: -40C to +85 ° C, 5V single analog power supply 

4, VDRIVE power supply voltage: 2.3V to 5V +30V input register protection, 8KV ESD 

5, the second-order anti-alias Analog filter 

6, on-chip precision reference source and reference voltage source buffer 

7, true bipolar analog input range: ± 10V, ± 5V 

8, integrated digital filter oversampling 

9, SNR 86dB (no oversampling) 95dB (64 times oversampling) 

10, QFP-64 package 12mm x 12mm, can be replaced by the AD7606 

Summary: the GX7606 high-precision The GX7606 high precision analog-to-digital converter can provide more accurate monitoring results, which can help to discover possible problems with the oil valve in time and ensure the stable operation of the system.
