PIN FUNCTIONS
LTC2641 – MSOP, DFN Packages
REF (Pin 1): Reference Voltage Input. Apply an external
reference at REF between 2V and V
CS (Pin 2): Serial Interface Chip Select/Load Input. When
CS is low, SCLK is enabled for shifting in data on DIN.
When CS 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.
CLR (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.
