National leads the 8- & 10-bit ADC space with best-in-class performance at the lowest power consumption! National's new ADC10D1500 10-bit, 3 Giga-sample per second (GSPS) single/1.5 GSPS dual analog-to-digital converter (ADC) delivers unequaled dynamic system-level performance and low power for wideband applications. At a frequency of 248 MHz, the ADC10D1500 provides the industry’s highest spurious-free dynamic range (SFDR) performance of 68 decibels relative to carrier (dBc) and 9.0 effective number of bits (ENOB). Running off a single supply voltage, the ADC10D1500 achieves this unparalleled level of performance while consuming a total power of only 3.1W. Offering similarly excellent performance in the 10-bit family is the ADC10D1000 which is a 2 GSPS single or 1.0 GSPS dual ADC.
The latest single ADC083000 converts one analog signal into 8 bits of data while consuming only 1.9 W at 3 GSPS. Its buffered version, the ADC08B3000, contains a 4 kilobyte buffer and consumes just 1.6 W at 3 GSPS. The dual ADC08D1500 consumes only 1.8 W for both channels simultaneously converting signals at 1.5 GSPS. This dual ADC can also be used as a single ADC at sampling speeds up to 3 GSPS by interleaving the internal ADC channels.
All converters in National's GSPS family of ADCs have similar pin configurations. Our customers can establish a standard board layout and reuse it across multiple designs as they upgrade or develop new products. This minimizes engineering costs and reduces development time when designing product spins..
In addition, National provides our customers with tools to speed up development cycle times. Our Reference Boards (e.g., ADC08D1500DEV and ADC083000RB) resemble data acquisition cards. They serve as platforms for our customers to develop their own application firmware as a starting point for their own proprietary designs. They are easy to use and eliminate the need for costly external measurement equipment. (See National.com/Xilinx for more information).
Typical ADC Family Features:
Dual-channel ADCs may run in an interleaved mode (DES Mode) to sample on one channel at twice the dual-channel sampling rate. For example, the ADC10D1000 can sample two channels at 1000 MSPS or one channel at 2000 MSPS.
There is an integrated 4K-byte buffer on the ADC08B3000 for burst data capture in ranging applications.
The ADC08D1520QML and ADC10D1000QML are High Reliability space grade versions of their commercial counterparts.
Internally terminated and buffered differential analog inputs simplify the design task of driving the ADC.
In multi-chip systems, ADCs can be synchronized by using the DCLK Reset feature and/or the AutoSync feature in the latest 10-bit generation.
The ADC performs a self-calibration upon power-up, which requires no additional design effort by the user, that trims internal components to maximize the linearity and dynamic performance.
A Test Pattern is provided at the digital outputs for system debug and testing.
A serial interface offers extended control settings such as channel offset and gain, common-mode, calibration setting, and aperture delay adjustment.
The data at the digital output may be clocked at a single data rate (SDR) or dual data rate DDR
The LVDS digital outputs may be Non-Demultiplexed or 1:2 Demultiplexed to ease FPGA data capture requirements.
All supplies run off of a single 1.9V ±0.1V power supply.
An exposed pad on the bottom of the 8-bit ADC package (128-pin LQFP) and the integrated copper heat slug inside the 10-bit ADC package (292-ball BGA) means that no additional heat sink is required for almost every application.
ADC Reference Boards are available to facilitate testing and design-in.
