Features

* D 240SPS Data Rate with 4MHz Clock D 20-Bit Effective Resolution D Input Multiplexer with Two Differential D D D D D D D D D Channels Pin-Selectable, High-Impedance Input Buffer ±5V Differential Input Range 0.0003% INL (typ), 0.0015% INL (max) Self-Calibrating Simple 2-Wire Serial Interface On-Chip

Applications

* A delta-sigma modulator and digital filter form the basis of the A/D converter. The analog modulator has a ±5V differential input range. An input multiplexer (mux) is used to select between two separate differential input channels. A buffer can be selected to increase the input impedance of the mea
