12-BIT, DUAL, ULTRALOW GLITCH, VOLTAGE OUTPUT

DIGITAL-TO-ANALOG CONVERTER

FEATURES

DESCRIPTION

•

2.7-V to 5.5-V Single Supply

The DAC7552 is

a 12-bit, dual-channel, volt-

age-output DAC with exceptional linearity and

monotonicity. Its proprietary architecture minimizes

undesired transients such as code-to-code glitch and

12-Bit Linearity and Monotonicity

Rail-to-Rail Voltage Output

Settling Time: 5 µs (Max)

channel-to-channel

crosstalk.

The

low-power

Ultralow Glitch Energy: 0.1 nVs

Ultralow Crosstalk: –100 dB

DAC7552 operates from a single 2.7-V to 5.5-V

supply. The DAC7552 output amplifiers can drive a

2-kΩ, 200-pF load rail-to-rail with 5-µs settling time;

the output range is set using an external voltage

reference.

Low Power: 440 µA (Max)

Per-Channel Power Down: 2 µA (Max)

Power-On Reset to Zero Scale

SPI-Compatible Serial Interface: Up to 50 MHz

Daisy-Chain Capability

The 3-wire serial interface operates at clock rates up

to 50 MHz and is compatible with SPI, QSPI,

Microwire™, and DSP interface standards. The out-

puts of all DACs may be updated simultaneously or

sequentially. The parts incorporate a power-on-reset

circuit to ensure that the DAC outputs power up to

zero volts and remain there until a valid write cycle to

the device takes place. The parts contain

power-down feature that reduces the current con-

sumption of the device to under 2 µA.

Asynchronous Hardware Clear

Simultaneous or Sequential Update

Specified Temperature Range: –40°C to 105°C

Small 3-mm × 3-mm, 16-Lead QFN Package

APPLICATIONS

The small size and low-power operation makes the

DAC7552 ideally suited for battery-operated portable

applications. The power consumption is typically

1.5 mW at 5 V, 0.75 mW at 3 V, and reduces to 1 µW

in power-down mode.
