CBM94AD34 12 bit, 370 MSPS /500 MSPS, 1.8 V analog-to-digital converter-Corebai Microelectronics (Beijing) Co., Ltd

CBM94AD34 is a 12 bit, single-chip sampling analog-to-digital converter (ADC) optimized for high performance, low power consumption, and ease of use. Its conversion rate can reach 500 MSPS, and it has good dynamic performance in broadband applications. All required functions are integrated on the chip, including sampling and holding amplifiers (SHA) and on-chip reference voltage sources, to provide a complete signal conversion solution. The VREF pin can be used to change the internal reference voltage or receive a reference voltage from the outside (the external reference mode needs to be turned on through the SPI port).
This ADC requires a 1.8V analog power supply and a differential clock to maintain excellent overall ADC performance. The digital output is compatible with LVDS (ANSI-644) and the data format is binary complement, Gray code, or offset binary. There is a data output clock to ensure that the corresponding data output has the correct timing.
This product is manufactured using SiGe BiCMOS technology, with 56 lead plastic packaging (QFN56), which can effectively replace ADI's AD9434BCPZ in the United States.
