II. AD65 Series: High-Speed, High-Precision Synchronous VFCs, Designed for High-End Measurement and Control

The AD65 series is ADI’s flagship range of high-speed, ultra-high-linearity synchronous voltage-to-frequency converters (SVFCs). Unlike traditional asynchronous VFCs, it employs an externally clocked, synchronous charge-balancing conversion architecture, thereby completely eliminating the constraints on conversion performance imposed by the accuracy of external passive components. It offers the best combination of speed and accuracy among the four series, with the core representative models being the AD652 and AD651, which are widely used in high-end precision industrial control and high-precision analogue-to-digital conversion applications.

1. Key Performance Parameters

- Conversion Rate: The AD651 achieves 2 MHz over full scale, whilst the AD652 reaches up to 4 MHz, placing them within the high-speed VFC category

- Linearity: At an output frequency of 100 kHz, the AD652 exhibits a typical non-linearity error of just 0.002% and a maximum error of 0.005%, far exceeding the accuracy of general-purpose VFCs

- Conversion Characteristics: The transfer function is absolutely monotonic, with no lost codes or non-linear offset issues; resolution and conversion time can be optimised as required

- Clock Architecture: Designed for external clock synchronisation; conversion accuracy is entirely determined by the high-precision clock, ensuring exceptional stability

2. Core Technical Advantages

The core advantage of the AD65 series lies in its synchronous charge-balanced conversion technology. By abandoning the asynchronous architecture of traditional RC oscillators and defining the full-scale frequency via an external high-precision clock, it completely eliminates conversion errors caused by temperature drift in resistors and capacitors, as well as insufficient accuracy. The device delivers a monotonically increasing output throughout the entire range with no conversion dead zone, making it suitable for high-precision closed-loop control systems. It also supports flexible configuration of conversion rate and resolution, allowing users to balance acquisition speed and accuracy according to application requirements, making it a core building block for precision analogue-to-digital conversion. The ceramic-packaged variant (AD652AQ) offers excellent environmental adaptability and is suitable for high-reliability applications such as defence and aerospace.
