ꢀow power operation: 500 μA @ 3 V, 600 μA @ 5 V

2-wire (I²C®-compatible) serial interface

2.5 V to 5.5 V power supply

The AD5305/AD5315/AD5325¹are quad 8-, 10-, and 12-bit

buffered voltage output DACs in a 10-lead MSOP that operate

from a single 2.5 V to 5.5 V supply, consuming 500 μA at 3 V.

Their on-chip output amplifiers allow rail-to-rail output swing

with a slew rate of 0.7 V/μs. A 2-wire serial interface that

operates at clock rates up to 400 kHz is used. This interface is

SMBus compatible at V_DD< 3.6 V. Multiple devices can be

placed on the same bus.

The references for the four DACs are derived from one

reference pin. The outputs of all DACs can be updated

simultaneously using the software LDAC function.

Guaranteed monotonic by design over all codes

Power-down to 80 nA @ 3 V, 200 nA @ 5 V

Three power-down modes

Double-buffered input logic

Output range: 0 V to V_REF

Power-on reset to 0 V

Simultaneous update of outputs (ꢀDAC function)

Software clear facility

Data readback facility

On-chip rail-to-rail output buffer amplifiers

Temperature range: −40°C to +105°C

The parts incorporate a power-on reset circuit, which ensures

that the DAC outputs power up to 0 V and remain there until a

valid write takes place to the device. There is also a software

clear function to reset all input and DAC registers to 0 V. The

parts contain a power-down feature that reduces the current

consumption of the devices to 200 nA @ 5 V (80 nA @ 3 V).

The low power consumption of these parts in normal operation

makes them ideally suited for portable battery-operated equip-

ment. The power consumption is 3 mW at 5 V, 1.5 mW at 3 V,

reducing to 1 ꢀW in power-down mode.

APPꢀICATIONS

Portable battery-powered instruments

Digital gain and offset adjustment

Programmable voltage and current sources

Programmable attenuators
