ADS1222IPW

The ADS1222IPW is designed as one kind of 24-bit analog-to-digital converter with 2-channel differential input multiplexer,it offers excellent performance and low power in a TSSOP-14 package.The ADS1222 is well-suited for demanding,high-resolution measurements, especially in portable systems and other space-saving and power-constrained applications.Also the ADS1222IPW supports 2.7V to 5.5V supplies.Power is typically less than 1mW in 3V operation and less than 1W during Standby mode.

Features of the ADS1222IPW are:(1)input multiplexer with two differential channels;(2)20-bit effective resolution;(3)240SPS data rate with 4MHz clock;(4)pin-selectable,high-impedance input buffer;(5)±5V differential input range;(6)0.0003% INL (typ),0.0015% INL (max);(7)self-calibrating;(8)simple 2-wire serial interface;(9)on-chip temperature sensor;(10)single conversions with standby mode;(11)low current consumption:300A;(12)analog supply:2.7V to 5.5V.It can be used in hand-Held instrumentation;portable medical equipment;industrial process control and weigh scales.

The absolute maximum ratings of the ADS1222IPW can be summarized as:(1)VDD to GND:-0.3 to +6 V;(2)input current:100(momentary) or 10(continuous) mA;(3)analog input voltage to GND:-0.3 to VDD+0.3 V;(4)digital input voltage to GND:-0.3 to VDD+0.3 V;(5)maximum junction temperature:+150 °C;(6)operating temperature range:-55 to +125°C;(7)storage temperature range:-60 to +150°C;(8)lead temperature (soldering,10s):+300 °C.If you want to know more information such as the electrical characteristics about the ADS1222IPW,please download the datasheet in www.seekdatasheet.com .
