General description

The ADC1113D125 is a dual-channel 11-bit Analog-to-Digital Converter (ADC) optimized

for high dynamic performance and low power at a sample rate of 125 Msps. Pipelined

architecture and output error correction ensure the ADC1113D125 is accurate enough to

guarantee zero missing codes over the entire operating range. Supplied from a 3 V

source for analog and a 1.8 V source for the output driver, it embeds two serial outputs.

Each lane is differential and complies with the JESD204A format. An integrated Serial

Peripheral Interface (SPI) allows the user to easily configure the ADC. A set of IC

configurations is also available via the binary level control pins taken, which are used at

power-up. The device also includes a programmable full-scale SPI to allow flexible input

voltage range of 1 V to 2 V (peak-to-peak).

Excellent dynamic performance is maintained from the baseband to input frequencies of

170 MHz or more, making the ADC1113D125 ideal for use in communications, imaging,

and medical applications.
