Product Summary
The AD7863ARSZ-3REEL is a high speed, low power, dual 14-bit A/D converter that operates from a single +5 V supply. The part contains two 5.2 μs successive approximation ADCs, two track/hold amplifiers, an internal +2.5 V reference and a high speed parallel interface. Four analog inputs are grouped into two channels (A and B) selected by the A0 input. Each channel has two inputs (VA1 and VA2 or VB1 and VB2), which can be sampled and converted simultaneously thus preserving the relative phase information of the signals on both analog inputs. The applications of the AD7863ARSZ-3REEL include AC Motor Control, Uninterrupted Power Supplies, Data Acquisition Systems, Communications.
