Description
AI
The ADC3644 device is a low-noise, ultra-low power, 14-bit, 125-MSPS dual-channel, high-speed analog-to-digital converter (ADC). Designed for low power consumption, the device delivers a noise spectral density of –153 dBFS/Hz, combined with very good linearity and dynamic range. The ADC3644 offers IF sampling support, which make the device an excellent choice for a wide range of applications. High-speed control loops benefit from the short latency of only one clock cycle. The ADC consumes only 82 mW/ch at 125 MSPS, and power consumption scales well with lower sampling rates.
The ADC3644 use a DDR or a serial CMOS interface to output the data offering lowest power digital interface, together with flexibility to minimize the number of digital interconnects. These devices are a pin-to-pin compatible family with different speed grades. These devices support the extended industrial temperature range of –40 to 105⁰C.
