AD7892 is a high speed, low power, 12-bit A/D converter that operates from a single +5 V supply. The part contains a 1.47 µs successive approximation ADC, an on-chip track/hold amplifier, an internal +2.5 V reference and on-chip versatile interface structures that allow both serial and parallel conn- ection to a microprocessor. The part accepts an analog input signal and converts it to a digital value.
The AD7892 is a high‑speed, low‑power 12‑bit analog‑to‑digital converter that operates from a single +5 V supply. It provides selectable input ranges (+10 V/+5 V, 0‑2.5 V, or +2.5 V) and features both parallel and serial output formats, making it suitable for microprocessor, microcontroller, and DSP applications.
The datasheet includes detailed specifications such as resolution, conversion time, power consumption, input/output pin functions, timing characteristics, and ordering information for the various AD7892 versions (A, B, S). It also provides guidelines for grounding, layout, and decoupling to achieve optimal performance.
