ADS830数据手册集成电路（IC）的模数转换器（ADC）规格书PDF

描述 Description

The ADS830 is a pipeline, CMOS Analog-to-Digital (A/D) converter that operates from a single +5V power supply. This converter provides excellent performance with a single-ended input and can be operated with a differential input for added spurious performance. This high performance converter includes an 8-bit quantizer, high bandwidth track/hold, and a high accuracy internal reference. It also allows for the user to disable the internal reference and utilize external references. This external reference option provides excellent gain and offset matching when used in multi-channel applications or in applications where DC full scale range adjustment is required. The ADS830 employs digital error correction techniques to provide excellent differential linearity for demanding imaging applications. Its low distortion and high SNR give the extra margin needed for medical imaging, communications, video, and test instrumentation. The ADS830 is specified at a maximum sampling frequency of 60MHz and a single-ended input range of 1.5V to 3.5V. The ADS830 is available in a SSOP-20 package and is pin-for-pin compatible with the 8-bit, 80MHz ADS831.
