Analog Devices AD573
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. The AD573 incorporates advanced integrated circuit design and processing technologies. The successive approximation function is implemented with I2L (integrated injection logic).| Part No. | AD573 |

DESCRIPTION
No external components are required to perform a full accuracy 10-bit conversion in 20 µs. 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 µs conversion cycle.
