AD7490BRUZ Typical application Circuitry

AD7490BRUZ

A 12-bit, 16-channel successive approximation, low-power analog-to-digital converter (ADC), the AD7490BRUZ is made by Analog Devices. This device has throughput rates up to 1 MSPS and runs off of a single 2.7V to 5.25V power source.

Keep the following things in mind while incorporating the AD7490BRUZ into an application circuit:

1. Power Supply Decoupling: It is advisable to use decoupling capacitors close to the power supply pins of the AD7490BRUZ to minimize noise. Ceramic capacitors are typically used due to their good high-frequency characteristics.

2. Reference Voltage: The AD7490BRUZ uses an internal 2.5V reference voltage. An external reference can be used for applications that need a different reference voltage. However, note that the external reference voltage range should be between 2.5V and VDD + 0.3V.

3. Input Signal Conditioning: Depending upon the nature of the analog input signals, input signal conditioning circuits such as low-pass filters may be necessary to eliminate high-frequency noise that could affect the accuracy of the conversion.

4. Data Transfer: The AD7490BRUZ utilizes a serial interface for data transfer, meaning it is critical to correctly manage the timing of the control signals (CS, SCLK, and CONVST) to ensure reliable data conversion and transmission.

5. Channel Selection: The AD7490BRUZ allows selection among its 16 single-ended analog input channels through software control. The selected channel's input voltage should stay within the converter's input voltage range to avoid damaging the device.

6. Temperature Considerations: As with all integrated circuits, the operating temperature can influence the performance of the AD7490BRUZ. Verify that the item works within the acceptable temperature range.

7. Layout Design: Good printed circuit board (PCB) layout design practices should be followed to reduce noise and improve the performance of the AD7490BRUZ. Analog and digital sections should be separated and grounded at a single point to avoid ground loops.

8. Thermal Management: Depending on the application, it may be necessary to consider thermal management solutions to prevent the AD7490BRUZ from overheating, especially in applications with a high ambient temperature or high power dissipation.

9. Protection: Including protection elements, such as transient-voltage suppressors, can be beneficial in protecting the AD7490BRUZ against electrostatic discharge or other harmful voltage spikes.

10. Compliance with Datasheet: Always ensure that the operation of the AD7490BRUZ complies with the recommendations and specifications laid out in the datasheet.

This includes but is not limited to, the input voltage, power supply voltage, and timing of the digital input. By adhering to these considerations and always referring back to the AD7490BRUZ datasheet, a reliable and effective application circuit can be achieved.
