High Performance 14-Bit, 125MSPS ADC
ISLA214P12
Features
The ISLA214P12 is a high performance 14-bit 125MSPS
analog-to-digital converter offering very high dynamic range
and low power consumption. It carries the export control
classification number 3A991.c.3 and can be exported
without a license to most countries, including China and
Russia. It is part of a pin-compatible family of 12- to 16-bit
A/Ds with maximum sample rates ranging from 125 to
500MSPS. This allows a design using the ISLA214P12 to
accommodate any of the other pin-compatible A/Ds with
minimal changes.
• License-free Import for most countries including China and
Russia (ECCN 3A991.c.3).
• Multi-ADC Support
- SPI Programmable Fine Gain and Offset Control
- Multiple ADC Synchronization
- Optimized Output Timing
• Clock Duty Cycle Stabilizer
• Nap and Sleep Modes
• Programmable Built-in Test Patterns
• SDR/DDR LVDS-Compatible or LVCMOS Outputs
• Data Output Clock
The ISLA214P12 is very flexible and can be designed into a wide
variety of systems. A serial peripheral interface (SPI) port allows
access to its extensive configurability as well as provides digital
control over various analog parameters such as input gain and
offset. Digital output data is presented in selectable LVDS or
CMOS formats and can be configured as full-width, single data
rate (SDR) or half-width, double data rate (DDR). Operating from a
1.8V supply, performance is specified over the full industrial
temperature range (-40°C to +85°C).
