ADS1212U

The ADS1212U is designed as one kind of 22-bit analog-to-digital converter device that is also designed for high resolution measurement applications such as (1)industrial process control; (2)instrumentation; (3)blood analysis; (4)smart transmitters; (5)portable instruments; (6)weigh scales; (7)pressure transducers. This device includes a 4 channel input multiplexer and is available in 24-pin DIP, 24-lead SOIC, and 28-lead SSOP packages.

Features of the ADS1212U are:(1)DELTA-SIGMA A/D converter; (2)22 bits no missing codes; (3)20 bits effective resolution at 10Hz and 16 bits at 1000Hz; (4)low power: 1.4mW; (5)differential inputs; (6)programmable gain amplifier; (7)SPI compatible ssi interface; (8)programmable cut-off frequency up to 6.25kHz; (9)internal/external reference; (10)on chip self-calibration; (11)ADS1213 includes 4 channel MUX.

The absolute maximum ratings of the ADS1212U can be summarized as:(1)AVDD to DVDD: -0.3 V to 6 V;(2)AVDD to AGND: -0.3 V to 6 V;(3)DVDD to DGND: -0.3 V to 6 V;(4)AGND to DGND: ±0.3 V;(5)REFIN Voltage to AGND: -0.3V to AVDD+0.3V;(6)Digital Input Voltage to DGND: -0.3V to DVDD+0.3V;(7)Digital Output Voltage to DGND: -0.3V to DVDD+0.3V;(8)Lead Temperature (soldering, 10s): +300°C;(9)Power Dissipation (Any package): 500 mW.
