DescriptionThe ADS7861E is one member of the ADS7861 series,it is a dual, 12-bit, 500kHz, analog-todigital converter with 4 fully differential input channels grouped into two pairs for high speed,simultaneous signal acquisition.Inputs to the sample-and-hold amplifiers are fully differential and are maintained differential to the input of the A/D converter. This provides excellent common-mode rejection of 80dB at 50kHz which is important in high noise environments.It also can be used in motor control,multi-axis positioning systems and 3-phase power control.
The ADS7861E offers a high speed, dual serial interface and control inputs to minimize software overhead.Features can be concluded into seven points:(1)4 input channels;(2)fully differential inputs;(3)guaranteed no missing codes;(4)1 MHz effective sampling rate;(5)low power:40 mW;(6)SSI series interface;(7)2 us total throughput per channel.
The specifications of the ADS7861E can be summarized as:(1)input voltage range-bipolar:-VREF to +VREF V;(2)input capacitance:15 pF;(3)power supply voltage:4.75 to 5.25 V;(4)power dissipation:25 mW;(5)quiescent current:5 mA;(6)channel-to-channel isolation:-80 dB;(7)power supply rejection ratio:0.5 LSB;(8)throughput rate:500 kHz;(9)spurious free dynamic range:72 dB.If you want to know more information such as the electrical characteristics about the ADS7861E,please download the datasheet in www.seekdatasheet.com .
