LTC2625 LINER [Linear Technology], LTC2625 Datasheet - Page 9

• Manufacturer Part Number: LTC2625
• Description: Octal 16-/14-/12-Bit Rail-to-Rail DACs in 16-Lead SSOP
• Manufacturer: LINER [Linear Technology]

PIN
BLOCK DIAGRA
GND (Pin 1): Analog Ground.
V
Voltage Output. The output range is 0V to V
REF (Pin 6): Reference Voltage Input. 0V ≤ V
CA2 (Pin 7): Chip Address Bit 2. Tie this pin to V
or leave it floating to select an I
(Table 2).
SCL (Pin 8): Serial Clock Input Pin. Data is shifted into the
SDA pin at the rising edges of the clock. This high
impedance pin requires a pull-up resistor or current
source to V

SDA (Pin 9): Serial Data Bidirectional Pin. Data is shifted
into the SDA pin and acknowledged by the SDA pin. This is
a high impedance pin while data is shifted in. It is an open-
drain N-channel output during acknowledgment. This pin
requires a pull-up resistor or current source to V
CA1 (Pin 10): Chip Address Bit 1. Tie this pin to V
or leave it floating to select an I
(Table 2).
CA0 (Pin 11): Chip Address Bit 0. Tie this pin to V
or leave it floating to select an I
(Table 2).
