C and D Technologies has introduced a new fully integrated, dual sampling 10Msample/s 14bit resolution A/D convertor. The ADSD-1410S complements C and D's 2Msample/s A/D convertor - the ADSD-1402S. The functionally complete ADSD-1410S is ideally suited for use in high-speed data acquisition systems that demand low noise and high performance.

Typical applications include medical instruments, radar I/Q, digital signal processors, plus other instrumentation and ATE for both commercial and military applications.

Housed in a standard 40-pin triple-wide SMT DIP, the ADSD-1410S is available in two versions.

The standard product is rated for use between ambient temperatures of 0 and +70C, whereas the ADSD-1410S-EX is suitable for use between -55 and +125C.

The module delivers no-missing-code performance across its full operating temperature range.

Ideal for both time and frequency domain applications, the ADSD-1410S has an input range of +/-2.5V and boasts a comprehensive list of standard features.

Included are two fast-settling sample/hold amplifiers, two 14bit A/D convertors, multiplexed output buffers, a precision reference, edge triggering, and all the necessary timing and control logic to operate from either two, or a single-start convert pulse.

The modules provide a range pin function that allows easy changes to be made to the analogue input range.

The digital output power supply of the ADSD-1410S is capable of directly driving either 5 or 3V logic systems.

The class leading specification of the ADSD-1410S includes a signal-to-noise ratio of 76dB and total harmonic distortion of -83dB, as well as superior integral nonlinearity and differential nonlinearity performance.

The modules, which require only a +/-5V supply and typically consume just 1.6W, are optimised for wideband frequency domain applications and are fully FFT tested.
