The ISLA216P is a family of low power, high performance
16-bit analog-to-digital converters. Designed with Intersil’s
proprietary FemtoCharge™ technology on a standard CMOS
process, the family supports sampling rates of up to
250MSPS. The ISLA216P is part of a pin-compatible portfolio
of 12 to 16-bit A/Ds with maximum sample rates ranging from
130MSPS to 500MSPS.
Features
• Single supply 1.8V operation
• Clock duty cycle stabilizer
• 75fs Clock jitter
• 700MHz Bandwidth
• Programmable built-in test patterns
• Multi-ADC support
A serial peripheral interface (SPI) port allows for extensive
configurability, as well as fine control of various parameters
such as gain and offset.
- SPI Programmable fine gain and offset control
- Support for multiple ADC synchronization
- Optimized output timing
Digital output data is presented in selectable LVDS or CMOS
formats. The ISLA216P is available in a 72-contact QFN
package with an exposed paddle. Operating from a 1.8V
supply, performance is specified over the full industrial
temperature range (-40°C to +85°C).
