AD7864AS-2规格书详情
GENERAL DESCRIPTION
The AD7864 is a high speed, low power, 4-channel simultaneous sampling 12-bit A/D converter that operates from a single +5␣ V supply. The part contains a 1.65 µs successive approximation ADC, four track/hold amplifiers, 2.5 V 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, ±5 V (AD7864-1), 0 V to 2.5 V, 0 V to 5 V for AD7864-2 and ±2.5␣ V (AD7864-3).
