130MSPS to 250MSPS Pin-Compatible ADC Family offers 77.5 to 75dBFS SNR at the Lowest Power Consumption and Features Multi-Channel Support
Intersil Corporation today expanded its growing family of high speed, low power analog-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 only 786mW – 40% less than competitive devices while maintaining SFDR of 87dBc at a 30MHz input frequency. This new low power series of ADCs significantly reduces 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, maximizing the utility of its power down features.
The ISLA216P series are members of Intersil's recently announced 12-, 14-, and 16-bit ADCs, and are pin-compatible with all other single-channel ADCs in the family. Pin-compatibility across sample rate and resolution facilitates design reuse and significantly reduces time-to-market.
The ISLA216P also provides multi-channel support so multiple ADCs can be precisely time-aligned, simplifying the design of simultaneously sampled multi-channel systems. 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 ISLA216P is an ideal choice.
Features and Specifications
The ISLA216P25 advances the state-of-the-art in high performance, low-power ADCs by offering best-in-class dynamic performance while consuming significantly less power than competing parts. At a sample rate of 250MSPS, the ISLA216P25 consumes just 786mW from its 1.8V supply and cpable of providing a signal-to-noise ratio (SNR) of 75.0dBFS and spurious free dynamic range (SFDR) of 87dBc for fin=30MHz. Furthermore, the ISLA216P25 is the only ADC in its class that is fully specified for input frequencies above 600MHz, allowing designers of undersampled or high IF systems to confidently utilize its 700MHz full-power bandwidth.
The new converters' breakthrough performance is combined with extensive configurability. 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 stabilizer and programmable clock divider simplify the challenge of clock distribution, and the programmable built-in test patterns improve reliability by enabling remote signal integrity self-test capability.
Pricing and Availability
The ISLA216P series is available now with sample rates ranging from 130MSPS to 250MSPS. The series comes in a 72-pin QFN package with exposed paddle. Pricing starts at $61.75 each in 1,000-unit quantities.
