• Manufacturer Part Number: LTC2704-12
• Manufacturer: LINER [Linear Technology]

PIN FUNCTIONS
LTC2641
REF (Pin 1): Reference Voltage Input. Apply an external
reference at REF between 2V and V
⎯ C ⎯ S (Pin 2): Serial Interface Chip Select/Load Input. When
⎯ C ⎯ S is low, SCLK is enabled for shifting in data on DIN.
When ⎯ C ⎯ S is taken high, SCLK is disabled, the 16-bit input
word is latched and the DAC is updated.
SCLK (Pin 3): Serial Interface Clock Input. CMOS and
TTL compatible.
DIN (Pin 4): Serial Interface Data Input. Data is applied
to DIN for transfer to the device at the rising edge of
SCLK.
⎯ C ⎯ L ⎯ R (Pin 5): Asynchronous Clear Input. A logic low clears
the DAC to code 0.
V
0V to V
V
5.5V.
GND (Pin 8): Circuit Ground.
Exposed Pad (DFN Pin 9): Circuit Ground. Must be sol-
dered to PCB ground.
OUT
DD
(Pin 7): Supply Voltage. Set between 2.7V and
(Pin 6): DAC Output Voltage. The output range is
REF

⎯ C ⎯ L ⎯ R (Pin 5): Asynchronous Clear Input. A logic low clears
the DAC to midscale.
V
0V to V
INV (Pin 7): Center Tap of Internal Scaling Resistors.
Connect to an external amplifi er’s inverting input in bipolar
mode.
R
amplifi er’s output in bipolar mode. The bipolar output
range is –V
