NAME
FUNCTION
20
REF+
Positive Reference Bypass. Bypass REF+ with a 0.1F capacitor to AGND. Also
bypass REF+ to REF- with a 2.2F and a 0.1F capacitor.
VREF+ = VCOM + VREF/2.
21
COM
Reference Common Bypass. Bypass COM to AGND with a 2.2F and a 0.1F
capacitor. VCOM = 13/25 x AVDD.
22
REF-
Negative Reference Bypass. Bypass REF- with a 0.1F capacitor to AGND.
Also bypass REF- to REF+ with a 2.2F and a 0.1F capacitor.
VREF- = VCOM - VREF/2.
24, 39
DGND
Digital Ground. DGND is the power return for DVDD. Connect all DGND
pins together.
25, 38
DVDD
Digital Power Input. DVDD powers the digital section of the converter, including
the parallel interface. Apply +2.7V to +5.25V to DVDD. Bypass DVDD to DGND
with a 0.1F capacitor. Connect all DVDD pins together.
26
D0
Digital I/O 0 of 12-Bit Parallel Data Bus. High impedance when RD = 1 or CS = 1.
27
D1
Digital I/O 1 of 12-Bit Parallel Data Bus. High impedance when RD = 1 or CS = 1.
28
D2
Digital I/O 2 of 12-Bit Parallel Data Bus. High impedance when RD = 1 or CS = 1.
29
D3
Digital I/O 3 of 12-Bit Parallel Data Bus. High impedance when RD = 1 or CS = 1.
30
D4
Digital I/O 4 of 12-Bit Parallel Data Bus. High impedance when RD = 1 or CS = 1.
31
D5
Digital I/O 5 of 12-Bit Parallel Data Bus. High impedance when RD = 1 or CS = 1.
32
D6
Digital I/O 6 of 12-Bit Parallel Data Bus. High impedance when RD = 1 or CS = 1.
33
D7
Digital I/O 7 of 12-Bit Parallel Data Bus. High impedance when RD = 1 or CS = 1.
34
D8
Digital Output 8 of 12-Bit Parallel Data Bus. High impedance when RD = 1 or
CS = 1.
35
D9
Digital Output 9 of 12-Bit Parallel Data Bus. High impedance when RD = 1 or
CS = 1.
36
D10
Digital Output 10 of 12-Bit Parallel Data Bus. High impedance when RD = 1 or
CS = 1.
37
D11
Digital Output 11 of 12-Bit Parallel Data Bus. High impedance when RD = 1 or
CS = 1.
40
EOC
End-of-Conversion Output. EOC goes low to indicate the end of a conversion. It
returns high on the next rising CLK edge or the falling CONVST edge.
41
EOLC
End-of-Last-Conversion Output. EOLC goes low to indicate the end of the
last conversion. It returns high when CONVST goes low for the next
conversion sequence.
42
RD
Read Input. Pulling RD low initiates a read command of the parallel data bus.
43
WR
Write Input. Pulling WR low initiates a write command for configuring the device
with D0–D7.
