AD7247A PIN FUNCTION DESCRIPTION (DIP PIN NUMBERS)
Pin
Mnemonic
Description
1
REF OUT
Voltage Reference Output. The internal 5 V analog reference is provided at this pin. To operate the part
with internal reference, REF OUT should be connected to REF IN.
2ROFSB
Output Offset Resistor for DAC B. This input configures the output ranges for DAC B. It is connected to
VOUTB for the +5 V range, to GND for the +10 V range and to REF IN for the ± 5 V range.
3VOUTB
Analog Output Voltage from DAC B. This is the buffer amplifier output voltage. Three different output
voltage ranges can be chosen: 0 V to +5 V, 0 V to +10 V and
±5 V. The amplifier is capable of developing
+10 V across a 2 k
resistor to GND.
4
DB11
Data Bit 11 (MSB).
5
DB10
Data Bit 10.
6
GND
Ground. Ground reference for all on-chip circuitry.
7–15
DB9-DB1
Data Bit 9 to Data Bit 1.
16
DB0
Data Bit 0 (LSB).
17
CSB
Chip Select Input for DAC B. Active low logic input. DAC B is selected when this input is active.
18
CSA
Chip Select Input for DAC A. Active low logic input. DAC A is selected when this input is active.
19
WR
Write Input. WR is an active low logic input which is used in conjunction with CSA and CSB to write data
to the DAC latches.
20
VDD
Positive Supply (+12 V to +15 V).
21
VOUTA
Analog Output Voltage from DAC A. This is the buffer amplifier output voltage. Three different output
voltage ranges can be chosen: 0 V to +5 V, 0 V to +10 V and
±5 V. The amplifier is capable of developing
+10 V across a 2 k
resistor to GND.
22
VSS
Negative Supply (0 V or –12 V to –15 V).
23
ROFSA
Output Offset Resistor for DAC A. This input configures the output ranges for DAC A. It is connected to
VOUTA for the +5 V range, to GND for the +10 V range and to REF IN for the
±5 V range.
24
REF IN
Voltage Reference Input. The common reference voltage for both DACs is applied to this pin. It is internally
buffered before being applied to both DACs. The nominal reference voltage for correct operation of the
AD7247A is 5 V.
