The AD7893 is a 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. It has a fast conversion speed, low power consumption, and a small size.
The AD7893 is a 12‑bit analog‑to‑digital converter that operates from a single +5 V supply and is offered in 8‑pin mini‑DIP and SOIC packages. It includes a 6 µs successive‑approximation converter, an on‑chip track/hold amplifier, and a high‑speed serial interface, making it suitable for battery‑powered and portable applications.
Key features include low power dissipation (typically 25 mW), selectable input voltage ranges (+10 V, +2.5 V, 0‑5 V, 0‑2.5 V), and a maximum throughput of 117 kHz. The device provides serial data and clock lines, a buffered +2.5 V reference input, and detailed timing specifications for conversion and bus operations.
