2.7-V to 5.5-V Single Supply  
The DAC7553 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  
DAC7553 operates from a single 2.7-V to 5.5-V  
supply. The DAC7553 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 Midscale  
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 at  
midscale 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.

a
The small size and low-power operation makes the  
DAC7553 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.
