Intersil has expanded its range of high-speed, low-power analogue-to-digital converters (ADCs) for communications and data-acquisition applications by introducing the 16-bit ISLA216P series of ADCs.

Designed using Intersil’s proprietary Femtocharge technology, the ISLA216P series features sample rates up to 250 megasamples per second (MSPS) with power consumption of 786mW, which is 40 per cent less than competitive devices, while maintaining SFDR of 87dBc at a 30MHz input frequency.

This low-power series of ADCs is designed to reduce heat dissipation and cooling requirements, enabling customers to lower overall system costs and increase reliability.

The ISLA216P also requires just 200 microseconds of wake-up recovery time from low power modes, maximising the utility of its power-down features.

The ISLA216P series is part of Intersil’s recently announced range of 12-, 14- and 16-bit ADCs and are pin-compatible with all other single-channel ADCs in the range.

Pin-compatibility across sample rate and resolution facilitates design reuse and also reduces time to market.

The ISLA216P also provides multi-channel support so that multiple ADCs can be precisely time-aligned, simplifying the design of simultaneously sampled multi-channel systems.

It is suitable for advanced applications that require multiple input channels, including radar array processing, broadband communications, data acquisition systems, software-defined radios and communications test equipment.

The 250 MSPS version of the ISLA216P25 was recently selected by Curtiss-Wright Controls Embedded Computing, a company that provides ruggedised product integration services for high-density data processing, for use in its new FMC-516 and FMC-518 quad-channel analogue-input FMC digitisers.

The FMC-516 and FMC-518 are designed to provide a low-cost modular method of designing embedded, FPGA-based signal processing nodes.

A serial peripheral interface (SPI) port allows access to the channel gain and offset adjustments as well as several power-saving modes.

The internal clock duty-cycle stabiliser and programmable clock divider are targeted to simplify the challenge of clock distribution and the programmable built-in test patterns to improve reliability by enabling remote signal integrity self-test capability.

As with each of Intersil’s prior ADC ranges, the ISLA216P is compatible with its existing evaluation system, developed to enable designers to analyse performance in both time and frequency domains.

The system features a modular design with one motherboard that supports multiple ADC types.

Matlab code is available for hardware-in-the-loop analysis and can capture greater than 1 megasample in a single, contiguous stream.

Users can download captured data to standard CSV files to apply specialised post processing.

The ISLA216P series is available now with sample rates ranging from 130 MSPS to 250 MSPS.

The series comes in a 72-pin QFN package with exposed paddle.
