ADS800U

The ADS800U is designed as a low power, monolithic 12-bit, 40MHz analog-to-digital converter utilizing a small geometry CMOS process. This converter includes a 12-bit quantizer, wideband track/hold, reference and three-state outputs. It operates from a single +5V power supply and can be configured to accept either differential or single-ended input signals.

It has five features. (1)Low power which would be 390mW. (2)Internal reference. (3)Wideband track/hold would be 65MHz. (4)Single +5V supply. (5)Package 28-lead SOIC and 28-lead SSOP. Those are all the main features.

Some absolute maximum ratings have been concluded as follow. (1)Its +Vs would be +6V. (2)Its analog input would be from 0V to Vs+300mV. (3)Its logic input would be from 0V to Vs+300mV. (4)Its case temperature would be +100°C. (5)Its junction temperature would be +150°C. (6)Its storage temperature would be +125°C. (7)Its external top reference voltage (REFT) would be max +3.4V. (8)Its external bottom reference voltage (REFB) would be min +1.1V. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics are concluded as follow. (1)Its resolution would be typ 12bits. (2)Its specified temperature range would be from 0°C to +70°C. (3)Its operating temperature range would be from -40°C to +85°C. (4)Its analog input differential full scale input range would be min +1.25V and max 3.25V. (5)Its common mode voltage would be typ +2.25V. (6)Its gain error would be typ +/-0.4% and max +/-1.5%. (7)Its gain drift would be typ +/-95ppm/°C. (8)Its power supply rejection of gain would be typ 0.01%FSR/% and max 0.15%FSR/%. (9)Its input offset error would be typ +/-2.6% and max +/-3.5%. (10)Its power supply rejection of offset would be typ 0.02 and max 0.15%FSR/%. And so on. If you have any question or suggestion or want to know more information please contact us for details.
