Exar Corporation MP1232A
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. The MP1230A series incorporates a unique decoding technique yielding lower glitch, higher speed and excellent accuracy over temperature and time.FEATURES

GENERAL DESCRIPTION
12-bit linearity is achieved without trimming. Outstanding features include: – Stability: integral and differential linearity tempcos are rated at 0.2 ppm/°C typical. Monotonicity is guaranteed over all 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.
