FEATURES  
DESCRIPTION  
The DAC121S101 is a full-featured, general purpose  
12-bit voltage-output digital-to-analog converter  
(DAC) that can operate from a single +2.7V to 5.5V  
supply and consumes just 177 µA of current at 3.6  
Volts. The on-chip output amplifier allows rail-to-rail  
output swing and the three wire serial interface  
operates at clock rates up to 30 MHz over the  
specified supply voltage range and is compatible with  
standard SPI™, QSPI, MICROWIRE and DSP  
interfaces. Competitive devices are limited to 20 MHz  
clock rates at supply voltages in the 2.7V to 3.6V  
range.

DAC121S101Q is AEC-Q100 Grade 1 qualified  
and is manufactured on an Automotive Grade  
Flow.

Wide Temperature Range of −40°C to +125°C  
Wide Power Supply Range of +2.7V to +5.5V  
Small Packages  
The supply voltage for the DAC121S101 serves as its  
voltage reference, providing the widest possible  
output dynamic range. A power-on reset circuit  
ensures that the DAC output powers up to zero volts  
and remains there until there is a valid write to the  
Power Down Feature

Automotive  
device.  
A
power-down feature reduces power  
consumption to less than a microWatt.  
The low power consumption and small packages of  
the DAC121S101 make it an excellent choice for use  
in battery operated equipment.  
The DAC121S101 is a direct replacement for the  
AD5320 and the DAC7512 and is one of a family of  
pin  
compatible  
DACs,  
including  
the  
8-bit  
DAC081S101 and the 10-bit DAC101S101. The  
DAC121S101 operates over the extended industrial  
temperature range of −40°C to +105°C while the  
DAC121S101Q operates over the Grade  
1
automotive temperature range of −40°C to +125°C.  
The DAC121S101 is available in a 6-lead SOT and  
an 8-lead VSSOP and the DAC121S101Q is  
available in the 6-lead SOT only.
