DESCRIPTION
q 24 BITS NO MISSING CODES The input channels are multiplexed. Internal buffering can be selected to provide very high input impedance for direct connection to transducers or low-level voltage signals. Burnout current sources are provided that allow for detection of an open or shorted sensor. An 8-bit Digital-to-Analog (D/A) converter provides an offset correction with a range of 50% of the Full-Scale Range (FSR). The Programmable Gain Amplifier (PGA) provides selectable gains of q ON-CHIP CALIBRATION q SPI™ COMPATIBLE q 2.7V TO 5.25V SUPPLY RANGE q 600µW POWER CONSUMPTION 1 to 128, with an effective resolution of 19 bits at a gain of 128. The A/D conversion is accomplished with a 2nd-order delta-sigma modulator and programmable Finite-Impulse Response (FIR) filter that provides a simultaneous 50Hz and 60Hz notch. The reference input is differential and can be used for ratiometric conversion. q UP TO EIGHT INPUT CHANNELS The serial interface is SPI compatible. Up to eight bits of data q UP TO EIGHT DATA I/O I/O are also provided that can be used for input or output.
