The SPT8100 is a high-performance, 16-bit analog-todigital converter that operates at a sample rate of up to 5 MSPS. Excellent dynamic performance and high linearity is achieved by a digitally calibrated pipelined architecture fabricated in CMOS process technology. A low-noise programmable gain amplifier (PGA) is also incorporated on chip. The PGA is digitally programmable in seven selected settings over a 0 to +19.5 dB range. The
