Austin Mixed-Signal Circuit Design

I’m developing a compact data-acquisition module and need a local electronics engineer in Austin who can take the mixed-signal front-end from concept to ready-to-fab documentation. The heart of the job is a clean, low-noise analog section feeding a high-resolution ADC, with the digital side handling basic buffering and a simple SPI or I²C hand-off to my existing microcontroller board.

We’ll meet in person for the initial requirements review and again when hardware is on the bench so rapid tweaks are possible. I already have rough performance targets—sampling at 1Hz, 12–16-bit resolution, and a 12V single-rail supply—but I’m looking for your guidance on component selection, input protection, and clocking strategy to hit those numbers without over-engineering.

Preferred tools are Altium Designer for schematic and PCB layout, LTspice or a similar simulator for the analog portions, and a quick Python script for bench-top validation, but I’m flexible if you can justify an alternative.

Deliverables:
• Complete schematic and PCB layout files
• BOM with manufacturer part numbers and estimated lead times
• Simulation results that demonstrate noise, linearity, and power figures meet spec
• Brief bring-up report after first prototype, highlighting any deviations and suggested fixes

If you’re comfortable coupling precision analog design with solid digital practice and can meet in the Austin vacinity, let’s talk timelines and milestone hand-offs.
