That 200kSPS rate places it in the sweet spot for industrial data-acquisition channels — fast enough to capture vibration or pressure transients without oversampling, but not so fast that the digital interface demands a high-speed serial engine. It accepts either 4 or 8 inputs, configurable as pseudo-differential or single-ended. The pseudo-differential mode rejects common-mode noise on the return path — useful when the sensor ground is a few hundred millivolts above the ADC ground, which happens on long cable runs in a factory panel. ## Supply rails and interface — what the board needs The analog supply is fixed at 5V; the digital supply runs from 2.7V to 5.5V, so it can interface directly with a 3.3V or 5V SPI bus without a level shifter. The 1:1 S/H:ADC ratio means each conversion samples and converts in one cycle — no pipeline delay, which simplifies the timing in a multiplexed system. The 24-TSSOP package (4.40mm width) is a common footprint for mixed-signal boards. The external reference requirement means the board designer controls the full-scale range — a precision reference like the REF50xx series pairs well here. The tube packaging is the standard delivery for prototype and low-volume builds; reel options exist for production runs.","metaTitle":"TLC3578IPW 14-bit SAR ADC, 200kSPS, 24-TSSOP","metaDescription":"Texas Instruments TLC3578IPW 14-bit SAR ADC, 200k sampling rate, 4/8 inputs, SPI interface, 24-TSSOP package.
