SPT8100

SPT8100 16-BIT, 5 MSPS CMOS A/D CONVERTER TECHNICAL DATA JANUARY 9, 2002 FEATURES 16-bit, 5 MSPS CMOS analog-to-digital converter On-chip PGA: gain range from 0 to 19.5 dB in seven selectable settings: 0 dB, +2.9 dB, +5.8 dB, +11.8 dB, +14.8 dB, +17.5 dB, +19.5 dB DLE: ±0.5 LSB, ILE: ±1.25 LSB SFDR: 94 dB @ ƒ IN = 900 kHz, –8.1 dBFS Internal sample-and-hold and voltage reference Power dissipation: 465 mW at 5 MSPS +5 V analog supply and +3.3 to +5.25 V digital output supply 44-lead LQFP plastic package APPLICATIONS Data acquisition systems IR imaging Scanners and digital copiers High-end CCD cameras Medical imaging Wireless communications Lab and test equipment Automatic test equipment DESCRIPTION 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 SPT8100 also features an on-chip internal sample-andhold and internal reference for minimal external circuitry. It operates from a single +5 V supply. Total power dissipation, 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 ava...
