Product Details

The AD7899 is a fast, low power, 14-bit A/D converter that operates from a single +5 V supply. The part contains a 2.0 µs successive approximation ADC, a track/hold amplifier, 2.5 V reference, on chip clock oscillator, signal conditioning circuitry and a high speed parallel interface. The part accepts analog input ranges of ±10 V , ±5 V, ±2.5 V, 0 V to +2.5 V and 0 V to +5 V. Overvoltage protection on the analog inputs for the part allows the input voltage to exceeded without damaging the parts or affecting a conversion in progress.
