The AD7892 is a single supply, 12-bit, 600 kSPS ADC. It is fabricated in Analog Devices' LC2MOS process, which combines precision bipolar circuits with low power CMOS logic. The AD7892-3 features a conversion time of 1.47 µs and a track/hold acquisition time of 200 ns, allowing for a throughput rate of up to 600 kSPS. The AD7892 operates from a single +5 V supply and consumes only 60 mW, making it ideal for low power and portable applications. It offers a high speed, flexible interface arrangement with both parallel and serial interfaces for easy connection to microprocessors, microcontrollers, and digital signal processors.
The AD7892 is a high‑speed, low‑power 12‑bit analog‑to‑digital converter from Analog Devices that operates from a single +5 V supply and offers both serial and parallel interfaces.
It provides conversion times as short as 1.47 µs, throughput up to 600 kSPS, selectable input ranges (±10 V, ±5 V, 0‑2.5 V, ±2.5 V), an on‑chip 2.5 V reference, and low typical power dissipation of 60 mW.
