AD7663:16位双极性250 kSPS PulSAR(R) CMOS ADC

AD7663: 16位双极性250 kSPS PulSAR(R) CMOS ADC

AD7663基于Pulsar内核,是一款双极性16位、250 kSPS电荷再分配SAR型模数转换器（ADC）,采用5 V单电源供电。它内置一个高速16位采样ADC、一个接受各种输入范围的电阻器输入标量、一个内部转换时钟、纠错电路,以及串行和并行系统接口。

Based on the Pulsar core, the AD7663 is a bipolar 16-bit, 250 kSPS, charge redistribution SAR Analog-to-Digital Converter that operates from a single 5 V power supply. It contains a high-speed 16-Bit sampling ADC, a resistor input scalar that allows various input ranges, an internal conversion clock, error correction circuits, and both serial and parallel system interface ports.
