Philips Semiconductors Linear Products Product specification 12-Bit multiplying D/A converter AM6012 DESCRIPTION The AM6012 12-bit multiplying Digital-to-Analog converter provides high-speed and 0.025% differential nonlinearity over its full commercial temperature range. The D/A converter uses a 3-bit segment generator for the MSBs in conjunction with a 9-bit R-2R diffused resistor ladder to provide 12-bit resolution without costly trimming processes. This technique guarantees a very uniform step size (up to ± LSB from the ideal), monotonicity to 12 bits and integral nonlinearity to 0.05% at its differential current outputs. The dual complementary outputs of the AM6012 increase its versatility, and effectively double the peak-to-peak output swing. Digital inputs, in addition, can be c [ ... ]
