GENERAL DESCRIPTION
The SPT774 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 SPT774 features 8
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 SPT774 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 SPT774 is available in 28-lead ceramic sidebrazed DIP,
PDIP and SOIC packages in the commercial temperature
range.
