16-Bit, 250MSPS/200MSPS/130MSPS ADC
ISLA216P
Features
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.
• 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).
• Nap and Sleep Modes
• 200µs Sleep Wake-up Time
• Data Output Clock
• DDR LVDS-Compatible or LVCMOS Outputs
• User-accessible Digital Temperature Monitor
