Analog Devices has introduced a precision medium bandwidth signal chain platform improving system performance for signal bandwidths of DC to approximately 500 kHz towards industrial and instrumentation applications. The new platform offers a host of complete signal chains with customisable options and a curated suite of development tools, such as LTspice® simulations, to simplify the design journey. These robust signal chains, designed for both time and frequency measurement precision, allow for end systems that can accept inputs from the widest array of sensor and measurement modalities from IEPE vibration and acceleration to temperature and pressure. The signal chains also support engineers in designing with confidence and tackling the most demanding precision instrumentation challenges in areas such as Condition Based Monitoring (CbM), large channel count or distributed data acquisition systems (DAQ), position and motor control, and sonar.
The signal chains included within the platform feature precision and power component selections that prioritise combined AC and DC accuracy design requirements, with options for single or multichannel systems as well as higher channel density for the largest channel count systems. Examples of precision medium bandwidth signal chain options provided with the platform include those that allow scaling of AC precision versus power for instrumentation, low latency options for motor control and position sensing, and highest density options using signal chain µModule SIP solutions or multichannel converters. Large channel count system designers can choose from signal chains where channel synchronisation is a priority, whether in channel-isolated or non-isolated systems.
Ket precision medium bandwidth signal chain features include:
- Optimising signal chain resolution and gain delivers the 16-bit to 24-bit accuracy required, across the widest range of sensor bandwidths, for amplitudes both small and large.
- Flexibility to prioritise between noise performance, signal bandwidth, and power enables reuse of optimum layout and multiple use cases of the circuitry with simple software updates.
- Options for higher channel densities give the ability to scale the precision measurements to distributed or centralised large channel count scenarios.
