This device accurately samples fullscale input signals up to Nyquist frequencies with no missing codes.
The dynamic performance of the ADS-930 is optimized to achieve a THD of –89dB and an SNR of 83dB.
Packaged in a small, 40-pin, ceramic TDIP, the functionally complete ADS-930 contains a fast-settling sample-hold amplifier, a subranging (three-pass) A/D converter, an internal reference, an on-board FIFO, timing and control logic, threestate outputs and error-correction circuitry.
Digital inputs/ outputs are TTL.
Requiring ±15V and +5V supplies, the ADS-930 typically dissipates 3.
5 Watts.
The unit is offered with a bipolar input range of ±5V or a unipolar input range of 0 to –10V.
Models are available for use in either commercial (0 to +70°C) or military (–55 to +125°C) operating temperature ranges.
Typical applications include radar, sonar, medical/graphic imaging, and FFT spectrum analysis.
