10-bit SAR ADC for harsh environments
The AD7580SE is a 10-bit successive-approximation ADC from the AD7580 series, sampling at 50k SPS with a differential input stage and a parallel data interface. Rated for -55°C to 125°C operation, it fits avionics, downhole, and satellite telemetry where the board sees the full military temperature swing — no derating needed at either end. The single 5V supply (4.75V to 5.25V for both analog and digital rails) simplifies power design in legacy 5V systems where a separate 3.3V or 1.8V rail isn't available.
Housed in a 28-CLCC (11.43x11.43 mm) ceramic package with surface-mount terminations — the ceramic body handles the thermal cycling of the -55°C to 125°C range without the CTE mismatch you'd see in a plastic SOIC. The parallel interface means the host controller reads the conversion result on a 10-bit bus without serial clock overhead — useful in FPGA or legacy DSP designs where a parallel port is already routed. RoHS non-compliant per the listing — if your assembly line is RoHS-exempt (military, aerospace, medical implant), the tin-lead termination is actually preferred for reliability under thermal stress.
