3 Description

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

+105⁰C.
