Specifications
DescriptionThe AD7705BR is designed as one kind of 3 V/5 V, 1 mW, 2-/3-channel, 16-bit, sigma-delta ADCs device that is complete analog front ends for low frequency measurement applications. And this device operates from a single 2.7 V to 3.3 V or 4.75 V to 5.25 V supply, and features a serial interface that can be configured for 3-wire operation.
Features of the AD7705BR are:(1)8-/10-Channel, High Resolution ADCs;(2)Factory-Calibrated;(3)Single Conversion Cycle Setting;(4)Programmable Gain Front End;(5)Simultaneous 50 Hz and 60 Hz Rejection;(6)Operation Can Be Optimized for Analog Performance (CHOP = 0) or Channel Throughput (CHOP = 1);(7)3-Wire Serial: SPI, QSPI, MICROWIRE, and DSP-Compatible Schmitt Trigger on SCLK;(8)Specified for Single 3 V and 5 V Operation.
The absolute maximum ratings of the AD7705BR can be summarized as:(1)AVDD to AGND:0.3 V to +7 V;(2)AVDD to DGND:0.3 V to +7 V;(3)DVDD to AGND:0.3 V to +7 V;(4)DVDD to DGND:0.3 V to +7 V;(5)AGND to DGND: -0.05 V to +0.05 V;(6)AVDD to DVDD:5 V to +5 V;(7)Analog Input Voltage to AGND:0.3 V to AVDD +0.3 V;(8)Reference Input Voltage to AGND:0.3 V to AVDD +0.3 V;(9)Total AIN/REFIN Current (Indefinite): 30 mA;(10)Junction Temperature: 150°C.
