ADC14071 Datasheet | National Semiconductor

Description The ADC14071 is a 14-bit, monotholic analog to digital converter capable of conversion rates up to 8 Megasamples per second. This CMOS converter uses a differential, piperlined architecture with digital error correction and an on-chip track-and-hold circuit to maintain superb dynamic performance with input frequencies up to 20MHz. Tested and guaranteed dynamic performance specifications provide the designer with known performance. The ADC14071 operates on a +5V single supply consuming just 380m W (typical). The Power Down feature reduces power consumption to 20m W, typical. The differential inputs provide a full scale input swing of ± VREF with the possibility of a single input. Full use of the differential input is remended for optimum perfomance. For ease of use, the reference input is single ended. This singleended reference input is converted on-chip to a differential reference configuration for use by the processing circuitry. Output data format is 14-bit straight binary. The ADC14071 may be used to replace many hybrid converters with a resultant saving of space, power and cost. The ADC14071 es in a 48-pin TQFP and is specified to operate over the industrial temperature range of - 40˚C to +85˚C.
