10-lead MSOP

The AD5302/AD5312/AD5322 are dual 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 230 μA at 3 V.

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

to-rail with a slew rate of 0.7 V/μs. The AD5302/AD5312/AD5322

utilize a versatile 3-wire serial interface that operates at clock

rates up to 30 MHz and is compatible with standard SPI®,

QSPI™, MICROWIRE™, and DSP interface standards.

Micropower operation: 300 μA @ 5 V (including

reference current)

The references for the two DACs are derived from two reference

pins (one per DAC). The reference inputs can be configured as

buffered or unbuffered inputs. The outputs of both DACs can be

Power-down to 200 nA @ 5 V, 50 nA @ 3 V

updated simultaneously using the asynchronous

input.

Guaranteed monotonic by design over all codes

0 V to V_REFoutput voltage

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. The parts contain a power-

down feature that reduces the current consumption of the

devices to 200 nA at 5 V (50 nA at 3 V) and provides software-

selectable output loads while in power-down mode.

On-chip rail-to-rail output buffer amplifiers

Qualified for automotive applications

The low power consumption of these parts in normal operation

makes them ideally suited for portable battery-operated

equipment. The power consumption is 1.5 mW at 5 V, 0.7 mW

at 3 V, reducing to 1 μW in power-down mode.
