FEATURES  
DESCRIPTION  
234  
•
Relative Accuracy: 0.5LSB  
Glitch Energy: 0.15nV-s  
Internal Reference:  
The DAC7565 is  
a
low-power, voltage-output,  
four-channel, 12-bit digital-to-analog converter (DAC).  
The device includes 2.5V, 2ppm/°C internal  
•
•
a
reference (enabled by default), giving a full-scale  
output voltage range of 2.5V. The internal reference  
has an initial accuracy of 0.02% and can source up to  
20mA at the VREFH/VREFOUT pin. The device is  
monotonic, provides very good linearity, and  
minimizes undesired code-to-code transient voltages  
(glitch). The DAC7565 uses a versatile 3-wire serial  
interface that operates at clock rates up to 50MHz.  
The interface is compatible with standard SPI™,  
QSPI™, Microwire™, and digital signal processor  
(DSP) interfaces.

Ultra-Low Power Operation: 1mA at 5V  
Wide Power-Supply Range: +2.7V to +5.5V  
12-Bit Monotonic Over Temperature Range  
The DAC7565 incorporates a power-on-reset circuit  
that ensures the DAC output powers up at either  
zero-scale or mid-scale until a valid code is written to  
the device. The device contains a power-down  
feature, accessed over the serial interface, that  
reduces the current consumption of the device to  
1.3µA at 5V. Power consumption is 2.9mW at 3V,  
reducing to 1.5µW in power-down mode. The low  
power consumption, internal reference, and small  
footprint make this device ideal for portable,  
battery-operated equipment.  
Settling Time: 10µs to ±0.024% Full-Scale

1.8V to 5.5V Logic Compatibility  
The DAC7565 is drop-in and functionally compatible  
with the DAC8165 and DAC8565, and functionally  
compatible with the DAC7564, DAC8164 and  
DAC8564. All these devices are available in a  
TSSOP-16 package.
