TABLE 1. 7805ALP PINOUT DESCRIPTION
PIN NUMBER
NAME
DIGITAL I/O DESCRIPTION
1V
IN
Analog input.
2
AGND1
Analog ground. Used internally as ground reference point.
3
REF
Reference input/output. 2.2 F tantalum capacitor to ground
4
CAP
Reference buffer capacitor. 2.2 F tantalum capacitor to ground.
5
AGND2
Analog ground.
6
D15 (MSB)
0
Data bit 15. Most Significant Bit (MSB) of conversion results. When STATUS is
HIGH*, D15 must not be driven high.
7
D14
0
Data bit 14. When STATUS is HIGH*, D14 must not be driven high.
8
D13
0
Data bit 13. When STATUS is HIGH*, D13 must not be driven high.
9
D12
0
Data bit 12. When STATUS is HIGH*, D12 must not be driven high.
10
D11
0
Data bit 11. When STATUS is HIGH*, D11 must not be driven high.
11
D10
0
Data bit 10. When STATUS is HIGH*, D10 must not be driven high.
12
D9
0
Data bit 9. When STATUS is HIGH*, D9 must not be driven high.
13
D8
0
Data bit 8. When STATUS is HIGH*, D8 must not be driven high.
14
DGND
Digital Ground
15
D7
0
Data bit 7. When STATUS is HIGH*, D7 must not be driven high.
16
D6
0
Data bit 6. When STATUS is HIGH*, D6 must not be driven high.
17
D5
0
Data bit 5. When STATUS is HIGH*, D5 must not be driven high.
18
D4
0
Data bit 4. When STATUS is HIGH*, D4 must not be driven high.
19
D3
0
Data bit 3. When STATUS is HIGH*, D3 must not be driven high.
20
D2
0
Data bit 2. When STATUS is HIGH*, D2 must not be driven high.
21
D1
0
Data bit 1. When STATUS is HIGH*, D1 must not be driven high.
22
D0 (LSB)
0
Data bit 0. Least Significant Bit (LSB) of conversion results. When STATUS is
HIGH*, D0 must not be driven high.
23
STATUS*
0
STATUS when HIGH indicates latchup protection is active and output data is
invalid. Capacitive loading should not exceed 1000 pF.
24
R/C
IWith CS LOW and BUSY HIGH, a falling edge of R/C initiates a new conversion.
When STATUS is HIGH*, CS and R/C must not be driven high.
25
CS
I
Internally OR’d with R/C. If R/C LOW, a falling edge on CS initiates a new conver-
sion. When STATUS is HIGH*, CS and R/C must not be driven high.
26
BUSY
0
At the start of a conversion, BUSY goes LOW and stays LOW until the conversion
is completed and the digital outputs have been updated.
27
DECPLNG
Supply voltage high speed decoupling pin. Decouple to ground with 1.0 F ceramic
capacitor.
28
V
S
Supply input. Nominally 5V. Decouple to ground with 10 F tantalum capacitor.
