ADS7863I数据手册集成电路（IC）的模数转换器（ADC）规格书PDF

描述 Description

DESCRIPTION
The ADS7863 is a dual, 12-bit, 1.5MSPS, analog-to-digital converter (ADC) with four fully differential input channels grouped into two pairs for high-speed, simultaneous signal acquisition. Inputs to the sample-and-hold (S/H) amplifiers are fully differential and are maintained differential to the input of the ADC. This architecture provides excellent common-mode rejection of 80dB at 50kHz, which is a critical performance characteristic in noisy environments.FEATURES
• Four Fully- or Six Pseudo-Differential Inputs
• SINAD: 70dB (min), THD: –75dB (max)
• Programmable and Buffered Internal 2.5V Reference
• Flexible Power-Down
