FUNCTIONAL DIAGRAMS

DESCRIPTION

The MPC506A is a 16-channel single-ended analog multi-

plexer, and the MPC507A is an 8-channel differential multi-

plexer.

The MPC506A and MPC507A multiplexers have input over-

voltage protection. Analog input voltages may exceed either

power supply voltage without damaging the device or dis-

turbing the signal path of other channels. The protection

circuitry assures that signal fidelity is maintained even under

fault conditions that would destroy other multiplexers. Analog

inputs can withstand 70V

signal levels and standard ESD

tests. Signal sources are protected from short circuits should

multiplexer power loss occur; each input presents a 1kΩ

resistance under this condition. Digital inputs can also sus-

tain continuous faults up to 4V greater than either supply

voltage.

These features make the MPC506A and MPC507A ideal for

use in systems where the analog signals originate from

external equipment or separately powered sources.

The MPC506A and MPC507A are fabricated with Burr-

Brown’s dielectrically isolated CMOS technology. The multi-

plexers are available in plastic DIP and plastic SOIC pack-

ages. Temperature range is –40/+85°C.

DISCUSSION OF SPECIFICATIONS DC CHARACTERISTICS Input Offset Voltage The static or dc transfer accuracy of transmitting the multiplexer input voltage to the output depends on the channel ON resistance (RON), the load impedance, the source impedance, the load bias current and the multiplexer leakage current. Bias current generates an input OFFSET voltage as a result of the IR drop across the multiplexer ON resistance and source resistance.
PAGE 6
Load (Output Device) Characteristics • Use devices with very low bias current. Generally, FET input amplifiers should be used for low-level signals less than 50mV FSR. Low bias current bipolar input amplifiers are acceptable for signal ranges higher than 50mV FSR. Bias current matching will determine the input offset. • The system dc common-mode rejection (CMR) can never be better than the combined CMR of the multiplexer and driven load.
PAGE 7
Factors which will degrade multiplexer and system DC CMR are: 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.
