The ADC0834CCN/NOPB is an 8-bit successive-approximation-register (SAR) ADC from Texas Instruments, packing a 4-channel input multiplexer (configurable as 2 differential or 4 single-ended inputs) and an SPI serial interface into a 14-pin DIP package. Its 31.25 kSPS sampling rate is modest by modern standards, but that is often enough for slow-moving signals like temperature, pressure, or panel potentiometer feedback — and the through-hole PDIP package makes it a natural fit for breadboard prototyping, one-off repairs, or legacy boards where a surface-mount part would require a layout spin. The single 4.5 V to 6.3 V supply rail powers both the analog and digital sections, so no separate AVDD/DVDD sequencing is needed — just a clean 5 V rail and an external reference voltage (the reference type is external) to set the full-scale range.
Package and board-fit — the 14-DIP rework reality
The 0.100-inch pin pitch is socket-compatible and easy to hand-solder or swap with a desoldering iron — no hot-air station required, and the part will survive multiple removal cycles without lifting a pad. The tube packaging (25 pieces per tube typical for this form factor) is standard for through-hole DIPs; the parts ship with the leads formed and ready for insertion.
