MP1230A

MP1230A/31A/32A CMOS Microprocessor Compatible Double-Buffered 12-Bit Digital-to-Analog Converter FEATURES Superior Ruggedized 1230 Series: 2 KV ESD Four Quadrant Multiplication Stable, More Accurate Segmented DAC Approach – 0.2 ppm/°C Linearity Tempco – 2 ppm/°C Max Gain Error Tempco – Lowest Sensitivity to Amplifier Offset – Lowest Output Capacitance (COUT = 80pF) www.DataSheet4U.com – Lower Glitch Energy Monotonic over Temperature Range Lower Data Bus Feedthrough @ CS = 1 VDD from +11 V to +16 V Latch-Up Free CMOS Technology 12-Bit Bus Version: MP1208/1209/1210 16-Bit Upgrade: MP7636A 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. The MP1230A series incorporates a unique decoding technique yielding lower glitch, higher speed and excellent accuracy over temperature and time. 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. ...
