AD7892AN-3 - Brand New Analog Devices IC Chips
-
Description
The AD7892AN-3 is a high speed, low power, 12-bit A/D converter that operates from a single +5 V supply. It has a 1.47 µs successive approximation ADC, an on-chip track/hold amplifier, an internal +2.5 V reference, and versatile interface structures that allow both serial and parallel connection to a microprocessor. The part accepts different analog input ranges depending on the model, including ±10 V or ±5 V for AD7892-1, 0 V to +2.5 V for AD7892-2, and ±2.5 V for AD7892-3. The AD7892AN-3 also features overvoltage protection on the analog inputs, allowing the input voltage to go beyond the specified range without damaging the ports. This model is fabricated in Analog Devices' Linear Compatible CMOS (LC2MOS) process, which combines precision bipolar circuits with low power CMOS logic. It is available in a 24-lead, 0.3" wide, plastic or hermetic DIP package, as well as a 24-lead SOIC package.
