DescriptionThe ADS7806U is one member of the ADS7806 family which designed as the low-power 12-bit sampling analogto-digital using state-of-the-art CMOS structu-res. It can be used in (1)battery-operated systems; (2)remote data acquisition; (3)isolated data acquisition; (4)simultaneous sampling, multi-channel syste-ms. It also features operation from 2.0V to 5V, a synchronous serial interface, and a pseudo-differential input.
Features of the ADS7806U are:(1)35mW max power dissipation;(2)50uW power down mode;(3)25ms max acquisition and conversion;(4)±1/2LSB max INL and DNL;(5)72dB min SINAD with 1kHz input;(6)±10V, 0V to +5V, and 0V to +4V input ranges;(7)single +5V supply operation;(8)parallel and serial data output;(9);(10)uses internal or external reference;(11)pin-compatible with 16-bit ADS7807;(12)28-pin 0.3" plastic DIP and SOIC.
The absolute maximum ratings of the ADS7806U can be summarized as:(1)ground voltage differences: DGND, AGND1, and AGND2:±0.3V;(2)VANA:7 V;(3)VDIG to VANA:+0.3 V;(4)VDIG:7 V;(5)digital inputs:-0.3V to VDIG +0.3 V;(6)maximum junction temperature:+165°C;(7)internal power dissipation:825 mW;(8)lead temperature (soldering, 10s):+300°C.
