detailed description (continued)
The following examples show how to program configuration registers CR0 and CR1 for different settings.
Example 1:
REGISTER
INDEX
D9 D8 D7 D6 D5 D4 D3 D2 D1 D0
COMMENT
CR0
0 0 1 1 0 1 0 0 0 0 Mono interrupt mode, use RD, write 0D0h to ADC
CR1
0 1 0 0 0 0 0 0 0 0 Use 2s complementary output, use RD, write 104h to ADC
Example 2:
CR0
0 0 1 1 0 1 0 0 0 0 Mono interrupt mode, use CSTART, write 0D0h to ADC
CR1
0 1 0 1 0 0 0 0 0 0 Use 2s complementary output, write 144h to ADC
Example 3:
CR0
0 0 1 1 0 1 0 1 0 0 Dual interrupt mode, use CSTART only, write 0D4h to ADC
CR1
0 1 0 1 0 0 0 0 0 0 Use 2s complementary output, write 144h to ADC
Example 4:
CR0
0 0 1 1 0 1 1 0 0 0 Mono continuous mode, use RD only, write 0D8h to ADC
CR1
0 1 0 0 0 0 0 0 0 0 Use 2s complementary output, write 104h to ADC
Example 5:
CRO
0 0 1 1 0 1 1 1 0 0 Dual continuous mode, use RD only, write 0DCh to ADC
CR1
0 1 0 0 0 0 0 1 0 0 Binary output, write 104h to ADC
analog input
input types
The four analog inputs can be configured as two pairs of differential inputs or four single-ended inputs by setting
the control register 0 bit 4 input type selection (dual or single channel).
differential input (CR0.4=1)
Up to two channels are available when the TLV1562 is programmed for differential input. The output data format
is bipolar when the device is operated in differential input mode.
single-ended input (CR0.4=0)
Up to four channels are available when the TLV1562 is programmed for single-ended input. The output data
format is unipolar when the device is operated in single-ended input mode.
