AD7248JNZ

AD7248 is a LC²MOS 12bit DACPORT. This is a complete 2-bit, voltage output, digital-to-analogue converter with output amplifier and Zener voltage reference on a monolithic CMOS chip. No external user trims are required to achieve full specified performance for the part. The AD72458 is a complete, voltage output, 12bit DAC on chip. This single chip design of the DAC reference and output amplifier is inherently more reliable than multichip designs. The AD7248A is fabricated in an all ion-implanted, high-speed linear, compatible CMOS (LC2MOS) process.
