Describes a 12-bit monolithic digital-to-analog converter with 70 ns settling time and a low output glitch content. The device is fabricated on a standard high speed digital process and needs no post-processing trimming to achieve the required accuracy and monotonicity. The output from this device is in the form of two complementary output currents, which may be terminated in resistive loads or amplified by a virtual earth input stage. Included on the chip are a temperature compensated voltage reference and reference loop amplifier. Essential external components are limited to a single current range setting resistor and decoupling/compensation capacitors.
