AD7650: 16位、570 kSPS、单极性CMOS逐次逼近型ADC
AD7650是一款低成本、16位、570 kSPS、单极性CMOS逐次逼近型模数转换器（ADC）,具有15位无失码特性,专为与性能相似但采样频率更高的ADC竞争而设计,AD7650具有低成本特性,是我们之前推出的高性能16位ADC（AD7664和AD7665）的绝佳补充。典型的交流性能：信纳比86 dB,总谐波失真-98dB （45 kHz时）。直流性能：积分非线性±6 LSB,15位无失码。最大功耗为115 mW（500 kSPS时）,典型值为21 µW（100 SPS时）。AD7650采用0 V至2.5 V范围内的差分输入。采用48引脚LQFP封装,对于电路板空间要求非常高的应用,可采用48引脚LFCSP封装。AD7650是第一款采用这种新封装的PulSAR ADC。
The AD7650 is a low cost, 16-bit, 570 kSPS, unipolar CMOS Successive Approximation ADC featuring 15-bits No Missing Codes. This model was developed to compete against ADCs with similar performance but at a higher sampling frequency. The AD7650 is an excellent, low cost complement to our previously introduced, high-performance 16-bit ADCs (AD7664 and AD7665).
Typical AC specifications are 86 dB SINAD and -98 THD @ 45 kHz. DC performance is ±6 LSB INL and 15-bits of no missing codes. Maximum power dissipation is 115 mW @500 kSPS and typically 21 µW @100 SPS. The AD7650 features differential inputs with a 0 V to 2.5 V input range. This model is available in the 48-lead LQFP or, for applications where board space is critical, the chip scale 48-lead LFCSP. The AD7650 is the first PulSAR ADC to feature this new package.
