ADC3543IRSBR

The ADC3541, ADC3542 and ADC3543 (ADC354x) family of devices are low-noise, ultra-low power, 14-bit, 10 to 65-MSPS, high-speed analog-to-digital converters (ADCs). Designed for low power consumption, these devices deliver a noise spectral density of –155 dBFS/Hz. The ADC354x offers great dc precision together with IF sampling support, which make these devices 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 79 mW at 65 MSPS, and the power consumption scales very well with lower sampling rates. The ADC354x uses an SDR, DDR or a serial CMOS interface to output the data offering the lowest power digital interface, together with the 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°C to +105°C.
