7 / 15 page MPC506A, MPC507A 7 SBFS018A www.ti.com Common-Mode Rejection (MPC507A Only) The matching properties of the load, multiplexer and source affect the common-mode rejection (CMR) capability of a differentially multiplexed system. CMR is the ability of the multiplexer and input amplifier to reject signals that are common to both inputs, and to pass on only the signal difference to the output. For the MPC507A, protection is provided for common-mode signals of ±20V above the power supply voltages with no damage to the analog switches. The CMR of the MPC507A and Burr-Brown's INA110 instrumentation amplifier (G = 100) is 110dB at DC to 10Hz with a 6dB/octave roll-off to 70dB at 1000Hz. This measure- ment of CMR is shown in the Typical Performance Curves and is made with a Burr-Brown INA110 instrumentation amplifier connected for gains of 500, 100, and 10. Factors which will degrade multiplexer and system DC CMR are: • Amplifier bias current and differential impedance mis- match • Load impedance mismatch • Multiplexer impedance and leakage current mismatch • Load and source common-mode impedance AC CMR roll-off is determined by the amount of common- mode capacitances (absolute and mismatch) from each signal line to ground. Larger capacitances will limit CMR at higher frequencies; thus, if good CMR is desired at higher frequencies, the common-mode capacitances and unbalance of signal lines and multiplexer to amplifier wiring must be minimized. Use twisted-shielded pair signal lines wherever possible.
