AM6012

12-Bit multiplying D/A converter

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.
