Description

The ADS1240E is designed as one kind of analog-to-digital converter which is precision, wide dynamic range,delta-sigma with 24-bit resolution operating from 2.7V to 5.25V power supplies.The delta-sigma A/D converter provides up to 24 bits of no missing code performance and effective resolution of 21 bits.The input channels are multiplexed and the programmable gain amplifier (PGA) provides selectable gains of 1 to 128,with an effective resolution of 19 bits at a gain of 128.

Features of the ADS1240E are as follow:(1)24 bits no missing codes;(2)simultaneous 50Hz and 60 Hz rejection(-90dB minimum);(3)0.0015% INL;(4)21 bits effective resolution(PGA=1),19 bits(PGA=128);(5)PGA gain from 1 to 128;(6)single cycle setting;(7)programmable data output rates;(8)external differential reference of 0.1 to 5 V;(9)on-chip calibration;(10)2.7V to 5.25V supply range;(10)up to eight input channels;(11)up to eight data I/O.And it can be used in industrial process control;weigh scales;liquid/gas chromatography;blood analysis;smart transmitters and portable instrumentation.

The absolute maximum ratings of the ADS1240E can be summarized as:(1)AVDD to DGND:-0.3V to +6V;(2)DVDD to DGND:-0.3V to +6V;(3)input current: 100mA,momentary;(4)DGND to AGND:-0.3V to 0.3V;(5)input current:10mA,continuous;(6)AIN:AGND -0.5V to AVDD+0.5V;(7)digital input voltage to DGND:-0.3V to DVDD+0.3V;(8)digital output voltage to DGND:-0.3V to DVDD+0.3V;(9)maximum junction temperature:+150°C;(10)operating temperature range:-40°C to +85°C;(11)storage temperature range:-60°C to +150°C;(12)lead temperature (soldering,10s):+300°C.If you want to know more information such as the electrical characteristics about the ADS1240E,please download the datasheet in www.seekdatasheet.com .
