The AD673 is a complete 8-bit successive approximation analog-to-digital converter consisting of a DAC, voltage reference, clock, comparator, successive approximation register (SAR) and 3-state output buffers--all fabricated on a single chip. No external components are required to perform a full accuracy 8-bit conversion in 20 s. The AD673 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 sub-surface Zener reference. Operating on supplies of +5 V and 12 V to 15 V, the AD673 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. The AD673 is available in two versions. The AD673J as specified over the 0C to +70C temperature range and the AD673S guarantees 1/2 LSB relative accuracy and no missing codes from 55C to +125C.
