NATIONAL Semiconductor Corporation, represented in Australia by Arrow Electronics Pty Ltd , has expanded its popular family of gigahertz-speed analogue-to-digital converters (ADCs) with the introduction of three new converters that offer the industry’s best performance with ultra-low power consumption.
The new products are the ADC08D1500, a dual 8-bit converter capable of sampling one analogue input at 3 giga-samples per second (GSPS) when operating in dual-edge sampling (DES) mode or two inputs at 1.5GSPS; the ADC08D500, a dual, 500 mega-samples per second (MSPS) 8-bit converter; and the ADC081500, a single version of the ADC08D1500.
These ADCs join the ADC08D1000 and ADC081000, two ultra-low-power gigahertz-speed ADCs introduced last year.
The new ADCs’ low power consumption of less than 2W enables engineers to design without fans and heat sinks, saving board space, reducing system cost and enhancing system reliability.
The ADC08D1500 typically achieves 7.2 effective number of bits (ENOB), 45.5dB signal-to-noise ratio (SNR) and 53.4dB spurious free dynamic range (SFDR) at 3GSPS with a 750MHz input signal.
The products guarantee no missing codes over the full operating temperature range of -40°C to +85°C.
The ultra-high-speed 8-bit family is well-suited for test and measurement equipment such as digital oscilloscopes, digital capture cards, spectrum analysers and communications transceiver applications.
