NAME
FUNCTION
1
OSA
DAC A Offset Adjust
2
OUTA
DAC A Output
3
RSTV
Reset Value Input
1: Connect to VDD to select midscale as the reset value.
0: Connect to DGND to select zero as the reset value.
4
LDAC
Load DACs A and B
5
CLR
Clear Input. Both DAC outputs go to zero or midscale. Clears both DAC internal registers (input
register and DAC register) to its predetermined (RSTV) state.
6
CS
Chip-Select Input
7
DIN
Serial Data Input. Data is clocked in on the rising edge of SCLK.
8
SCLK
Serial Clock Input
9
DGND
Digital Ground
10
DOUT
Serial Data Output
11
PDL
Power-Down Lockout. Disables shutdown of both DACs when low.
12
REF
Reference Output. Reference provides a 2.465V (MAX5233) or 1.234V (MAX5232) nominal output.
13
AGND
Analog Ground
14
VDD
Positive Power Supply. Bypass VDD with a 0.1F capacitor in parallel with a 4.7F capacitor to
AGND, and bypass VDD with a 0.1F capacitor to DGND.
15
OUTB
DAC B Output
16
OSB
