DESCRIPTION
The SPT8100 is a high-performance, 16-bit analog-to-
digital converter that operates at a sample rate of up to
5 MSPS. Excellent dynamic performance and high linear-
ity is achieved by a digitally calibrated pipelined architec-
ture fabricated in CMOS process technology.
A low-noise programmable gain amplifier (PGA) is also in-
corporated on chip. The PGA is digitally programmable in
seven selected settings over a 0 to +19.5 dB range. The
SPT8100 also features an on-chip internal sample-and-
hold and internal reference for minimal external circuitry.
It operates from a single +5 V supply. Total power dissipa-
tion, including internal reference, is 465 mW. A separate
digital output supply pin is provided for +3.3 V or 5 V logic
output levels. The SPT8100 is available in a 44-lead LQFP
package over the industrial temperature range of –40 °C to
+85 °C.
