GENERAL D ESCRIP TIO N  
T he DAC312 series of 12-bit multiplying digital-to-analog con-  
verters provide high speed with guaranteed performance to  
0.012% differential nonlinearity over the full commercial oper-  
ating temperature range.  
High compliance and low drift characteristics (as low as  
10 ppm/°C) are also features of the DAC312 along with an ex-  
cellent power supply rejection ratio of ±.001% FS/%V. Oper-  
ating over a power supply range of +5/–11 V to ±18 V the  
device consumes 225 mW at the lower supply voltages with an  
absolute maximum dissipation of 375 mW at the higher supply  
levels.  
T he DAC312 combines a 9-bit master D/A converter with a  
3-bit (MSBs) segment generator to form an accurate 12-bit D/A  
converter at low cost. T his technique guarantees a very uniform  
step size (up to ±1/2 LSB from the ideal), monotonicity to  
12-bits and integral nonlinearity to 0.05% at its differential cur-  
rent outputs. In order to provide the same performance with a  
12-bit R-2R ladder design, an integral nonlinearity over tem-  
perature of 1/2 LSB (0.012%) would be required.  
With their guaranteed specifications, single chip reliability and  
low cost, the DAC312 device makes excellent building blocks  
for A/D converters, data acquisition systems, video display driv-  
ers, programmable test equipment and other applications where  
low power consumption and complete input/output versatility  
are required.  
T he 250 ns settling time with low glitch energy and low power  
consumption are achieved by careful attention to the circuit de-  
sign and stringent process controls. Direct interface with all  
popular logic families is achieved through the logic threshold  
terminal.
