ADC1213D065/080/105/125:
Dual12-bit ADC; 65, 80, 105 or 125 Msps
The ADC1213D is a dual channel 12-bit Analog-to-Digital Converter (ADC) optimized for high dynam
icperformances and low power at sample rates up to 125 Msps. Pipelined architecture and output error correction ensure the ADC1213D is accurate enough to guarantee zero missing codes over the entire operating range. Supplied from a 3.3 V source for analog and a 1.8 V source for the output driver, it can output data in serial mode, because of the two lanes of differential outputs, which are compliant with the JESD204A standard. An integrated Serial Peripheral Interface (
SPI) allows the user to easily configure the ADC. A
setof IC configurations is also available via the binary level control pins, which are used at power-up. The device also includes a programmable gain amplifier with flexible input voltage range.
