Fast, Complete 12-bit Up Compatible A/d Converter With Sample/hold

The SPT674 is a complete, 12-bit successive approximation A/D converter manufactured in CMOS technology. The de- vice is an improved version of the HADC574Z. Included on chip are an internal reference, Clock and a sample-and-hold. The S/H is an additional feature not available on similar devices. The SPT674 features 15 s (max) conversion time of 10 or 20 V input signals. Also, a three-state output Buffer is added for direct Interface to an 8, 12, or 16-bit P bus. The SPT674 has standard bipolar and unipolar input ranges of 10 V and 20 V that are controlled by a bipolar offset pin and laser trimmed for specified linearity, gain and offset accuracy. The power supply is +5 V. The device also has an optional mode control voltage which may be used depending on the application. With a maximum dissipation of 120 mW at the specified voltages, power consumption is about five times lower than that of currently available devices. The SPT674 is available in a 28-lead ceramic sidebrazed DIP package in the commercial temperature range. By Unkown
