DESCRIPTION
The ADS5413 is a low power, 12-bit, 65-MSPS, CMOS pipeline analog-to-digital converter (ADC) that operates from a
single 3.3-V supply, while offering the choice of digital output levels from 1.8 V to 3.3 V. The low noise, high linearity, and
low clock jitter makes the ADC well suited for high-input frequency sampling applications. On-chip duty cycle adjust circuit
allows the use of a non-50% duty cycle. This can be bypassed for applications requiring low jitter or asynchronous
sampling. The device can also be clocked with single ended or differential clock, without change in performance. The
internal reference can be bypassed to use an external reference to suit the accuracy and low drift requirements of the
application.
The device is specified over full temperature range (−40°C to +85°C).
