AD7824/AD7828

UNIPOLAR OPERATION

The analog input range for any channel of the AD7824/ AD7828

is 0 V to 5 V as shown in the unipolar operational diagram of Fig-

ure 10. Figure 11 shows the designed code transitions which

occur midway between successive integer LSB values (i.e.,

1/2 LSB, 3/2 LSB, 5/2 LSB, FS 3/2 LSBs). The output code is

Natural Binary with 1 LSB = FS/256 = (5/256) V = 19.5 mV.

4 V Operation

TIMING AND CONTROL

The AD7824/AD7828 has two digital inputs for timing and

control. These are Chip Select (CS) and Read (RD). A READ

operation brings CS and RD low which starts a conversion on

the channel selected by the multiplexer address inputs (see

Table I). There are two modes of operation as outlined by the

timing diagrams of Figures 14 and 15. Mode 0 is designed for

microprocessors which can be driven into a WAIT state. A

READ operation (i.e., CS and RD are taken low) starts a con-

version and data is read when conversion is complete. Mode l

does not require microprocessor WAIT states. A READ operation

initiates a conversion and reads the previous conversion results.

Unipolar 0 V to 5 V Operation

BIPOLAR OPERATION

The circuit of Figure 12 is designed for bipolar operation. An

AD544 op-amp conditions the signal input (V_IN) so that only

positive voltages appear at AIN 1. The closed loop transfer

function of the op amp for the resistor values shown is given

below:

The analog input range is 4 V and the LSB size is 31.25 mV.

The output code is complementary offset binary. The ideal
