HotRIO F-HSE-ADC-DDR (DDR ADC board)

Datasheet for this product available here

The HotRIO F-HSE-ADC-DDR is a standalone expansion board with two ADC ICs, each providing two independent channels. Each channel supports sampling rates up to 2 MHz at 20-bit resolution.

The board is designed for integration with the HotRIO F-HSC-DDR standalone controller for analog-to-digital conversion. This solution is ideal for use-cases where standalone ADCs must be provided without any other equipment, allowing deployment of a single HotRIO-compliant node with the ADCs, without the need for additional infrastructure such as a Eurocard chassis.

The F-HSE-ADC-DDR board is intended for applications where analog signals must be digitized in close proximity to their source, such as in remote or distributed environments. In scenarios where sensors are deployed in the field, this board enables local analog-to-digital conversion, thereby minimizing the need for extended analog cabling, which can be prone to noise and signal degradation. By performing digitization at the source, only digital data needs to be transmitted, significantly reducing susceptibility to interference.

Unlike the full HotRIO eurocard chassis, which is large and includes a wide range of I/O options, this board is compact and focused. It provides the essential HotRIO functionality for ADC applications without the bulk and complexity of the full chassis, making it ideal for installations where space is limited and only ADC capability is required.
