ADI AD7862ARSZ-3REEL

The AD7862 is a high-speed, low-power, dual 12-bit A/D converter powered by a single +5 V supply. The device contains two 4 μs successive approximation ADCs, two track/hold amplifiers, an internal +2.5 V reference, and a high-speed parallel interface. There are four analog inputs, divided into two channels (A and B), selected by the A0 input. Each channel has two inputs (VA1 and VA2 or VB1 and VB2) that can be sampled and converted simultaneously, thus preserving the relative phase information of the signals on the two analog inputs. The device accepts analog input ranges of ±10 V (AD7862-10), ±2.5 V (AD7862-3), and 0 - 2.5 V (AD7862-2). The overvoltage protection of the device's analog inputs allows the input voltage to reach ±17 V, ±7 V, or +7 V without damage.
