PRODUCTION DATA
The ADC3544 is a low noise, ultra-low power 14-bit high-speed ADC supporting sampling rates up to 125 MSPS. It offers good DC precision together with IF sampling support which makes it ideally suited for a wide range of applications. The ADC3544 is equipped with an on-chip internal reference option but it also supports the use of an external, high precision 1.6 V voltage reference or an external 1.2 V reference which is buffered and gained up internally. Because of the inherent low latency architecture, the digital output result is available after only one clock cycle. Single ended as well as differential input signaling is supported.
An optional programmable digital down converter enables external anti-alias filter relaxation as well as output data rate reduction.
The ADC3544 uses a SDR or DDR as well as a 2-wire or 1-wire serial CMOS interface to output the data offering lowest power digital interface together with the flexibility to minimize the number of digital interconnects. The ADC3544 includes a digital output formatter which supports output resolutions from 14 to 20-bit. The device is a pin-to-pin compatible with different speed grades.
The device features and control options can be set up either through pin configurations or via SPI register writes.
