ISLA212P Datasheet, PDF (1/35 Pages) Intersil Corporation – 12-Bit, 250MSPS/200MSPS/130MSPS ADC

12-Bit, 250MSPS/200MSPS/130MSPS ADC
ISLA212P
The ISLA212P is a series of low power, high performance
12-bit analog-to-digital converters. Designed with Intersil’s
proprietary FemtoCharge™ technology on a standard CMOS
process, the series supports sampling rates of up to 250MSPS.
The ISLA212P is part of a pin-compatible family of 12 to 16-bit
A/Ds with maximum sample rates ranging from 130MSPS to
500MSPS.
A serial peripheral interface (SPI) port allows for extensive
configurability, as well as fine control of various parameters
such as 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). The ISLA212P 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).
