Selecting the right components for your precision signal chain doesn’t have to be a tedious process. With the help of Signal Chain Designer, you can identify the ideal products for your application faster, easier and with confidence. This tool streamlines this process by offering an interactive selection table where you can compare parts, apply selection filters, and choose parameters that matter to your design. After selecting a part, you can view various simulated results in Signal Chain Designer to evaluate whether it meets your performance targets for noise, accuracy, power consumption, and bandwidth.
Here's how to effectively use the "Part Selection" feature of the tool:
1. Accessing the Selection Table
When Signal Chain Designer generates an initial circuit recommendation, each stage comes with a suggested part. If you want to explore alternatives, clicking either the part name or the pencil icon opens the full selection table for that stage. This table lists all compatible components along with their key parameters.

2. Adding and Customizing Parameters
The selection table includes a "Choose Parameters" button that lets you reveal additional electrical specifications beyond the default columns.
- Bias Current
- CMRR
- Current Noise Density
- Settling Time
- Open-loop Gain
- Temp Range
This allows you to tailor the table to highlight the specs most relevant to your design.

3. Sorting and Filtering to Narrow Down Devices
If the table contains numerous parts, use the built‑in sorting and filtering tools:
- Sort by clicking column headers (e.g., sort by lowest noise, highest bandwidth)
- Filter using numeric thresholds (e.g., show only devices with bias current < 10 pA)
This filtering capability makes it much faster to narrow down the components that fit your requirements.
4. Selecting and Applying a New Device
- Select the desired part number.
- Signal Chain Designer will automatically substitute it into your signal chain.
- You can immediately simulate the updated signal chain to view the impact on noise, DC error, gain, power, or input range.
