Description

1
AVDD
Positive Analog Supply Pin. Voltage range is from 5 V to 15 V.
2
VOUTD
Buffered Analog Output Voltage of DAC D.
3
VOUTC
Buffered Analog Output Voltage of DAC C.
4
VREFN
Negative DAC Reference Input. The voltage appliedto this pindefines the zero-scale
output. Allowable range is AVSS to VREFP 2.5 V.
5
7
VREFP
Positive DAC Reference Input. The voltage appliedto this pin defines the full-scale
output voltage. Allowable range is AVDD 2.5 V to VREFN + 2.5 V.
6
8
VOUTB
Buffered Analog Output Voltage of DAC B.
7
9
VOUTA
Buffered Analog Output Voltage of DAC A.
8
10
AVSS
Negative Analog Supply Pin. Voltage range is from 0 V to 15 V.
9
11
GND
Ground Reference Pin.
10
12
SDIN
Serial Data Input. Data must bevalidonthe risingedgeofSCLK. This input isignored
whenCSis high.
11
13
SCLK
Serial Clock Input. Data is clockedinto the input register on the rising edge of SCLK.
12
14
CS
Active Low Chip Select Pin. This pin must be active for data to be clocked in. This pin
is logically OR’ed with the SCLK input and disables the serial data input when high.
13
5, 6, 15, 16, 17
NC
No Internal Connection.
14
18
LDAC
Active Low, Asynchronous Load DAC Input. The data currently contained in the
serial input register is transferred out to the DAC data registers on the falling edge
of LDAC, independent of CS. Input data must remainstable while LDAC is low.
15
19
CLR
Active Low Input. Sets input register and DAC registers to zero-scale (0x000) or
midscale (0x800), depending on the state of CLRSEL. The data in the serial input
register is unaffected by this control.
16
20
CLRSEL
Determines the action of CLR. If high, a clear command sets the internal DAC
registers to midscale (0x800). If low, the registers are set to zero (0x000).
