Description

AD0

Wiper Terminal of RDAC0. V_SS≤ V_W0≤ V_DD.

B Terminal of RDAC0. V_SS≤ V_B0≤ V_DD.

A Terminal of RDAC0. V_SS≤ V_A0≤ V_DD.

I²C Device Address 0. AD0 and AD1 allow four AD5253/AD5254 devices to be addressed.

Write Protect, Active Low. V_WP≤ V_DD+ 0.3 V.

Wiper Terminal of RDAC1. V_SS≤ V_W1≤ V_DD.

B Terminal of RDAC1. V_SS≤ V_B1≤ V_DD.

SDA

A Terminal of RDAC1. V_SS≤ V_A1≤ V_DD.

Serial Data Input/Output Pin. Shifts in one bit at a time upon positive clock edges. MSB loaded first. Open-drain

MOSFET requires pull-up resistor.

V_SS

Negative Supply. Connect to 0 V for single supply or –2.7 V for dual supply, where V_DD– V_SS≤ +5.5 V. If V_SSis used

rather than grounded in dual supply, V_SSmust be able to sink 35 mA for 26 ms when storing data to EEMEM.

SCL

A Terminal of RDAC2. V_SS≤ V_A2≤ V_DD.

B Terminal of RDAC2. V_SS≤ V_B2≤ V_DD.

Wiper Terminal of RDAC2. V_SS≤ V_W2≤ V_DD.

Serial Input Register Clock Pin. Shifts in one bit at a time upon positive clock edges. V_SCL≤ (V_DD+ 0.3 V). Pull-up

resistor is recommended for SCL to ensure minimum power.

DGND

AD1

Digital Ground. Connect to system analog ground at a single point.

I²C Device Address 1. AD0 and AD1 allow four AD5253/AD5254 devices to be addressed.

A Terminal of RDAC3. V_SS≤ V_A3≤ V_DD.

B Terminal of RDAC3. V_SS≤ V_B3≤ V_DD.

Wiper Terminal of RDAC3. V_SS≤ V_W3≤ V_DD.

V_DD

Positive Power Supply Pin. Connect +2.7 V to +5 V for single supply or 2.7 V for dual supply, where V_DD– V_SS≤ +5.5 V.

_DDmust be able to source 35 mA for 26 ms when storing data to EEMEM.
