Part Description

The AD673 is a complete 8-bit successive approximation analog-to-digital converter consisting of a DAC, voltage refer- ence, 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 ac- curacy 8-bit conversion in 20 µs. The AD673 incorporates advanced integrated circuit design and processing technologies. The successive approximation function is implemented with I2 L (integrated injection logic). Laser trim- ming 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 µs conversion cycle. DATA READY indicates comple- tion of the conversion. The AD673 is available in two versions. The AD673J as speci- fied over the 0°C to +70°C temperature range and the AD673S guarantees ±1/2 LSB relative accuracy and no missing codes from –55°C to +125°C. Two package configurations are offered. All versions are also of- fered in a 20-pin hermetically sealed ceramic DIP. The AD673J is also available in a 20-pin plastic DIP.
