Plan a PCM1794A audio DAC around differential current outputs, external I/V stages, hardware format pins, clock relationships and controlled analog startup.

Review TCA9554 GPIO initialization, weak internal pull-ups, output latches and interrupt servicing without assuming TCA9534 behavior or an event queue.

Plan DRV8872 motor control with the correct input truth table, external sense resistor, sleep timing and fault handling without assuming newer-family features.

Plan a TPS63031 fixed 3.3 V buck-boost supply with correct FB sensing, input-dependent load capability, mode control and realistic shutdown expectations.

Use ADS1119 configuration, START/SYNC commands and data-ready timing to keep sixteen-bit results associated with the intended channel, gain and reference.

Plan ADS131E08 simultaneous acquisition with the correct rate-dependent word length, channel slots, reference settings, settling time and serial readout budget.

Decode TMP125 ten-bit signed temperature correctly and review SPI framing, SI shutdown control, one-shot operation and the freshness of conversion results.

Review TPS27082L load-switch design with the correct external gate network, controlled rise time, logic limits and realistic inrush and protection expectations.

Plan an INA821 instrumentation-amplifier stage with the correct gain resistor, bias-current paths, REF drive and input common-mode versus output headroom.

Plan a TPS62160 buck supply with correct sensing, component selection, startup checks and power-good logic that does not mistake shutdown for readiness.
