4 Channel, Simultaneous Sampling Hi-Speed, 14-Bit ADC
Introduction
The AD7865 is a high speed, low power, four-channel simultaneous sampling 14-bit A/D converter that operates from a single +5 V supply. The part contains a 2.4µs successive approximation ADC, four track/hold amplifiers, 2.5V reference, on chip clock oscillator, signal conditioning circuitry and a high speed parallel interface. The input signals on four channels are sampled simultaneously thus preserving the relative phase information of the signals on the four analog inputs. The part accepts analog input ranges of ±10 V, ±5V (AD7865-1), 0 to 2.5 V, 0 to 5 V for AD7865-2 and ±2.5 V (AD7865-3).
The evaluation board is compatible with the EVALUATION BOARD CONTROLLER.
