AM601212-Bit multiplying D/A converter
776August 31, 1994 853-0904 13721
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 the device 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/% ∆V.
The devices will work from +5, -12V to ±18V rails, with as low as
230mW power consumption typical.
