MCP6C04

5.2.2

ANALOG LEVEL SHIFTER

The MCP6C04 can be used to shift analog voltages

from a high positive voltage down to a low voltage.

Many possibilities exist; Figure 5-11 is just one possible

implementation.

The input attenuator (R1 and R2) allow a wider range of

voltages to be measured. No resistor is placed

between V1 and the noninverting input, so that the input

current IBP doesn’t cause an offset shift. The attenuator

resistors' accuracy and values may affect the circuit's

gain error and offset.

The +2.5V reference level allows bidirectional voltage

sensing; it needs to be very low impedance and reject

glitches on the supply or ground (see Figure 5-3 for

recommendations on this part of the circuit).
