ADS-947GE Summary of contents
Page 1
... The functionally complete ADS-947 contains a fast-settling sample/hold amplifier, a subranging (two-pass) A/D converter, an internal reference, timing/control logic, and error-correction circuitry. Digital input and output levels are TTL. The ADS-947 only requires the rising edge of a start convert pulse to operate. Requiring only +5V and –5.2V supplies, the ADS-947 typically dissipates just 2 Watts. The device is offered with a bipolar input range of ± ...

... Bypass all power supplies to ground with 4.7µF tantalum capacitors in parallel with 0.1µF ceramic capacitors. Locate the bypass capacitors as close to the unit as possible. 2. The ADS-947 achieves its specified accuracies without the need for external calibration. If required, the device’s small initial offset and gain errors can be reduced to zero using the adjustment circuitry shown in Figures 2 and 3 ...

... To avoid interaction, offset must be adjusted before gain. The ranges of adjustment for the circuits in Figures 2 and 3 are guaranteed to compensate for the ADS-947’s initial accuracy errors and may not be able to compensate for additional system errors. A/D converters are calibrated by positioning their digital outputs exactly on the transition point between two adjacent digital output codes. This can be accomplished by connecting LED’ ...

... For sampling rates less than 10MHz, the start pulse can be wider than 85nsec, however a minimum pulse width low of 15nsec should be maintained. A 10MHz clock with a 20nsec positive pulse width is used for all production testing. Electrically-insulating, thermally-conductive "pads" may be installed underneath the package. Devices should be soldered ...
