Product Summary
The AD7892ARZ-3REEL 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 connection to a microprocessor. The part accepts an analog input range of ±10 V or ±5 V (AD7892-1), 0 V to +2.5 V (AD7892-2) and ±2.5 V (AD7892-3). Overvoltage protection on the analog inputs for the AD7892ARZ-3REEL allows the input voltage to go to ±17 V or ±7 V respectively without damaging the ports.
