The AD7895 is a fast 12-bit ADC that operates from a single +5 V supply and is housed in a small 8-pin mini-DIP and 8-pin SOIC. The part contains a 3.8 µs successive approximation A/D converter, an on-chip track/hold amplifier, an on-chip clock and a high speed serial interface. Output data from the AD7895 is provided via a high speed, serial interface port. This two-wire serial interface
The AD7895 is a fast 12‑bit analog‑to‑digital converter that operates from a single +5 V supply. It integrates a successive‑approximation converter, on‑chip track/hold amplifier, reference input, and a two‑wire serial interface in an 8‑pin package. Key features include low power consumption (20 mW max), selectable input ranges (±10 V, ±2.5 V, 0‑2.5 V), conversion times as short as 3.8 µs, and high‑speed serial data output suitable for battery‑powered applications.
