8-bit SAR ADC with integrated MUX and sample-and-hold
The ADC0809CCV is an 8-bit successive-approximation-register (SAR) analog-to-digital converter from Texas Instruments, integrating an 8-channel multiplexer, sample-and-hold, and the ADC core in a single 28-pin PLCC package. It accepts eight single-ended analog inputs through the internal MUX, with a 1:1 sample-and-hold to ADC ratio, and outputs conversion results via an 8-bit parallel data bus. The SAR architecture delivers a conversion rate suitable for moderate-speed data acquisition in industrial control, instrumentation, and embedded systems where a simple parallel interface simplifies microcontroller or FPGA integration.
Supply range, reference, and temperature grade
Both the analog and digital supply rails share the same 4.5 V to 6 V range, simplifying single-supply operation — a single 5 V rail powers the entire converter, with an external reference setting the full-scale input span. Surface-mount assembly in the 28-PLCC (J-Lead) footprint, with a supplier device package size of 11.51 mm x 11.51 mm — the J-lead form factor provides visual solder-joint inspection access and moderate board-level reliability under thermal cycling.
