DESCRIPTION
NAME
TLV1571
TLV1578
AGND
21
25
Analog ground
AIN
23
27
I
ADC analog input (used as single analog input channel for TLV1571)
AVDD
22
26
Analog supply voltage, 2.7 V to 5.5 V
CH0 – CH7
–
1– 4,
29–32
I
Analog input channels
CLK
4
8
I
External clock input
CS
1
5
I
Chip select. A logic low on CS enables the TLV1571/ TLV1578.
CSTART
18
22
I
Hardware sample and conversion start input. The falling edge of CSTART starts sampling and
the rising edge of CSTART starts conversion.
DGND
5
9
Digital ground
DVDD
6
10
Digital supply voltage, 2.7 V to 5.5 V
D0 – D7
8 –12,
13 –15
12 –16,
17–19
I/O
Bidirectional 3-state data bus
D8/A0
16
20
I/O
Bidirectional 3-state data bus. D8/A0 along with D9/A1 is used as address lines to access CR0
and CR1 for initialization.
D9/A1
17
21
I/O
Bidirectional 3-state data bus. D9/A1 along with D8/A0 is used as address lines to access CR0
and CR1 for initialization.
INT/EOC
7
11
O
End-of-conversion/interrupt
MO
28
O
On-chip MUX analog output
NC
24
Not connected
RD
3
7
I
Read data. A falling edge on RD enables a read operation on the data bus when CS is low.
REFM
20
24
I
Lower reference voltage (nominally ground). REFM must be supplied or REFM pin must be
grounded.
REFP
19
23
I
Upper reference voltage (nominally AVDD). The maximum input voltage range is determined by
the difference between the voltage applied to REFP and REFM.
WR
2
6
I
Write data. A rising edge on the WR latches in configuration data when CS is low. When using
software conversion start, a rising edge on WR also initiates an internal sampling start pulse.
When WR is tied to ground, the ADC in nonprogrammable (hardware configuration mode).
