GENERAL DESCRIPTION  
The MP1230A series are superior pin for pin replacements  
for the 1230 series. The MP1230A series is manufactured using  
advanced thin film resistors on a double metal CMOS process  
which promotes significant improvements in reliability, latch-up  
free performance and ESD protection.  
temperature ranges. Scale factor tempco is a low 2 ppm/°C  
maximum.  
Low Output Capacitance: Due to smaller MOSFET switch  
geometries allowed by decoding, the output capacitance at  
IOUT1 and IOUT2 is a low 80pF / 40pF and 25pF / 65 pF. This  
less than half the competitive DAC 1230 series. Lower ca-  
pacitance allows the MP1230A series to achieve settling  
times faster than 1 µs for a 10 V step.  
The MP1230A series incorporates a unique decoding tech-  
nique yielding lower glitch, higher speed and excellent accuracy  
over temperature and time. 12-bit linearity is achieved without  
trimming. Outstanding features include:  
Low Sensitivity to Output Amplifier Offset: The linearity er-

MP1230A series over conventional R-2R DACs.  
Stability: integral and differential linearity tempcos are rated  
The MP1230A series uses a circuit which reduces transients  
at 0.2 ppm/°C typical. Monotonicity is guaranteed over all  
in the supplies caused by DATA bus transitions at  
= 1.
