The AD7810 is a high-speed, low-power, 10-bit ADC in an 8-lead microSOIC/DIP package. It operates from a supply voltage range of 2.7 V to 5.5 V and has a conversion time of 2.3 µs.
The AD7810 is a 10‑bit successive‑approximation ADC with a 2.3 µs conversion time, low‑power single‑supply operation (2.7 V‑5.5 V) and an inherent track‑and‑hold function. It offers a serial interface compatible with most microcontrollers and optional automatic power‑down to reduce consumption in battery‑powered applications.
The document provides full electrical specifications, timing characteristics, pin descriptions, typical connection diagrams, and guidelines for power‑vs‑throughput, operating modes, and microprocessor interfacing. Ordering information for the DIP, SOIC and microSOIC packages is also included.

| Supply Voltage Range | 2.7 V to 5.5 V |
| Input Leakage Current | +1 pA max |
When enabled, the AD7810 powers down at the end of a conversion and wakes up on the next conversion start, reducing power consumption at low throughput rates.
