The AD7810 is a high speed, low power, 10-bit analog-to-digital converter (ADC) with a supply voltage range of 2.7V to 5.5V and a conversion time of 2.3μs. It is available in a compact, 8-lead microSOIC/DIP package.
The AD7810 is a high‑speed, low‑power 10‑bit analog‑to‑digital converter that operates from a single 2.7 V to 5.5 V supply. It features a 2.3 µs successive‑approximation conversion time, inherent track‑and‑hold, a pseudo‑differential input, and a two‑wire serial interface compatible with most microcontrollers. The device is specified over a temperature range of –40 °C to +105 °C and includes an automatic power‑down mode to reduce consumption in low‑throughput applications.
Key specifications include a 10‑bit resolution, 350 kSPS maximum sampling rate, 270 µW power consumption at 10 kSPS, and a small 8‑lead microSOIC package. The datasheet provides detailed pin descriptions, timing characteristics, absolute maximum ratings, and typical connection diagrams for system integration.
