Datasheet for Texas Instruments TLC3574/78 and TLC2574/2578 ADCs, detailing specifications, pin functions, and performance.
The TLC3574/78 and TLC2574/2578 are high‑performance, low‑power CMOS analog‑to‑digital converters from Texas Instruments. The TLC3574/78 provides 14‑bit resolution, while the TLC2574/2578 offers 12‑bit resolution, both supporting up to 200 KSPS throughput. They operate from a single 5 V analog supply and feature an SPI/DSP‑compatible serial interface with pins CS, FS, SCLK, SDI and a 3‑state SDO.
These devices are available in multiple packages (DW, PW, N, etc.) and include an on‑chip analog multiplexer. Absolute‑maximum ratings specify supply voltages from –0.3 V to 6.5 V and operating temperatures from –40 °C to 85 °C. Detailed electrical characteristics cover input voltage range (±10 V), power consumption (5.8 mA normal, 20 µA power‑down), and conversion times.
