The flash architecture means the conversion happens in a single clock cycle — no pipeline delay — so this part is suited for applications where latency matters, like digitizing a fast transient before the input changes. The single-ended input with an external reference gives you control over the full-scale range — set the reference voltage to match your sensor's output swing and the 8-bit resolution divides that span into 256 steps. ## Package and board integration — 20-pin DIP The 20-PDIP supplier package designation means the pin 1 index is at the notch end — orient the socket or solder pads accordingly before populating the board. Because the digital and analog supplies share the same 5 V rail, a single decoupling capacitor (0.1 µF ceramic close to each supply pin) is usually enough to keep the internal comparator noise below one LSB. The parallel data bus is 8 bits wide — route the eight output lines with matched trace lengths if the receiving logic is more than a few inches away to avoid setup-time violations at 500k conversions per second.","metaTitle":"Analog Devices MX7821KEPP 8-Bit ADC, 500k SPS, 20-DIP","metaDescription":"MX7821KEPP 8-bit flash ADC with track/hold, 500k samples per second, parallel interface.
