Industry’s Fastest
14-Bit ADC
The ISLA214P50 is a 14-bit, 500MSPS ADC that consumes 63% less
power while sampling at a rate 25% higher than any other 14-Bit
ADC. The ISLA214P50 was designed using Intersil’s proprietary
FemtoCharge™ technology and operates from a 1.8V power
supply. The converter’s ultra-high sample rate and resolution
improve sensitivity and accuracy, while the decrease in power
consumption allows simplified thermal and power system design.
This ADC also combines breakthrough performance with extensive
configurability, making it one of the most flexible and easy-to-use
ADCs on the market.

16-Bit, 250MSPS: ISLA216P25
Industry’s Lowest Power
16-Bit, 250MSPS ADC
The ISLA216P is a series of low power, high performance 16-bit
analog-to-digital converters. Designed with Intersil’s proprietary
FemtoCharge™ technology on a standard CMOS process, the
series is the only pin-compatible family of 16-bit ADCs that support
sampling rates from 40 to 250MSPS. The ISLA216P is part of a
pin-compatible family of 12- to 16-bit ADCs with maximum sample
rates ranging from 130 to 500MSPS.
The ISLA216P also provides multi-channel support so multiple
ADCs can be matched precisely and aligned in time, simplifying
the design of multi-channel systems. For advanced applications
that benefit from multi-channel design, including data acquisition
systems, radar array processing, broadband communications,
software defined radios, and communications test equipment, the
ISLA216P is an ideal choice.
