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 configured to accept all popular logic families.

While AM6012 requires a reference input of 1mA for a 4mA full-scale current, operation is nearly independent of power supply voltage shifts. The power supply rejection ratio is ±0.001% FS/% DV. The devices will work from +5, -12V to ±18V rails, with as low as 230mW power consumption typical.
