The AD573 is a complete 10-bit successive approximation analog-to-digital converter consisting of a DAC, voltage reference, clock, comparator, successive approximation register (SAR) and three state output buffers--all fabricated on a single chip. No external components are required to perform a full accuracy 10-bit conversion in 20 s. The AD573 incorporates advanced integrated circuit design and processing technologies. The successive approximation function is implemented with I2L (integrated injection logic). Laser trimming of the high stability SiCr thin-film resistor ladder network insures high accuracy, which is maintained with a temperature compensated subsurface Zener reference. Operating on supplies of +5 V and 12 V to 15 V, the AD573 will accept analog inputs of 0 V to +10 V or 5 V to +5 V. The trailing edge of a positive pulse on the CONVERT line initiates the 20 s conversion cycle. DATA READY indicates completion of the conversion. HIGH BYTE ENABLE (HBE) and LOW BYTE ENABLE (LBE) control the 8-bit and 2-bit three state output buffers.
