LTC2626 LINER [Linear Technology], LTC2626 Datasheet - Page 10

• Manufacturer Part Number: LTC2626
• Description: 16-/14-/12-Bit Rail-to-Rail DACs with I2C Interface
• Manufacturer: LINER [Linear Technology]

LTC2606/LTC2616/LTC2626
PIN
CA2 (Pin 1): Chip Address Bit 2. Tie this pin to V
or leave it floating to select an I
(Table 1).
SDA (Pin 2): Serial Data Bidirectional Pin. Data is shifted
into the SDA pin and acknowledged by the SDA pin. This
pin is high impedance while data is shifted in. Open drain
N-channel output during acknowledgment. SDA requires
a pull-up resistor or current source to V
SCL (Pin 3): 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
CA0 (Pin 4): Chip Address Bit 0. Tie this pin to V
or leave it floating to select an I
(Table 1).
CA1 (Pin 5): Chip Address Bit 1. Tie this pin to V
or leave it floating to select an I
(Table 1).

LDAC (Pin 10): Asynchronous DAC Update. A falling edge
on this input after four bytes have been written into the part
immediately updates the DAC register with the contents of
the input register. A low on this input without a complete
32-bit (four bytes including the slave address) data write
transfer to the part does not update the DAC output.
Software power-down is disabled when LDAC is low.
Exposed Pad (Pin 11): Ground. Must be soldered to PCB
