SNR is key spec for speedy sampling
convertor
The ADS-953 sampling ADC optimises signal return paths and provides internal, local decoupling to obtain an outstanding -95dB peak harmonic specification and 76uV RMS noise-level performance.
Datel's newly introduced ADS-953 sampling A/D convertor optimises signal return paths and provides internal, local decoupling to obtain an outstanding -95dB peak harmonic specification and 76uV RMS noise-level performance Signal-to-noise ratio, one of the most important specifications for imaging applications, is an impressive 93dB

Novel regulation makes dual DC/DCs more flexible
Datel's new BWR-5/3.3, 33W Series mixed-voltage, dual-output (3.3 and 5V) DC/DC convertors feature a novel output structure that does not limit output current in the traditional manner.
More current from industry-standard convertors
Datel's new USN Series D5 SIPs are nonisolated DC/DC convertors that accept a 5V input (4.5 to 5.5V input range) and deliver 1.5, 1.8, 2.5 or 3.3V outputs at either 8 or 10A.
Additionally, the ADS-953 offers no missing codes over the full operating temperature range.
Using various mixed-signal devices, the ADS-953 packages an 18bit, 1Msample/s analogue-to-digital convertor in a functionally complete 32-pin TDIP ceramic hybrid.
The proprietary gate array provides all the timing and control logic necessary to operate from a single edge-triggered start convert pulse, while providing the output data with no pipeline delays.
This provides a key benefit as pipeline delays, often associated with high-resolution monolithic multipass convertors, cannot be tolerated in many high-end, leading-edge applications that are time-critical.
Applications for the ADS-953 include numerous high-end instrumentation and imaging applications (life sciences, medical, industrial scientific instruments, military) and spectrum applications such as communications, radar and sonar.
The A/D convertor benefits from very low power consumption of just 1.45W from +/-15 and +/-5V supplies.
It is available for operation over both the commercial (0 to +70C) and military (-55 to +110C) temperature ranges.
High-reliability versions are also available on request.
