Introduction
AD1865 is a complete dual-channel 18-bit DAC offering excellent THD+N and SNR with no external components required. It contains two complete signal channels. This results in in-phase voltage or current output signals and eliminates the need for output demultiplexing circuitry. The monolithic AD1865 die integrates CMOS logic elements, bipolar and MOS linear elements, and laser-trimmed thin-film resistor elements, all fabricated using the ABCMOS process. The DACs on the AD1865 employ a partially segmented architecture. The top four MSBs of each DAC are divided into 15 unit elements. The 14 LSBs are generated using standard R-2R techniques. The segmented resistors and R-2R resistors are laser-trimmed to provide extremely low THD. This architecture minimizes errors at major code transitions, resulting in low output glitch and eliminating the need for external deglitching circuitry. When used in current output mode, the AD1865 provides two ±1 mA output signals. Each channel features a high-performance output amplifier. These amplifiers achieve fast settling and high slew rate, delivering ±3V signals with load currents up to 8mA. Each output amplifier has short-circuit protection and can withstand indefinite short circuits to ground. The AD1865 is designed to balance two competing sets of requirements: channel separation and DAC matching. High channel separation is achieved through careful layout. At the same time, the two channels of the AD1865 are designed to ensure matched gain and linearity, as well as tracking over time and temperature. This guarantees performance in stereo and multiple-DAC-per-channel applications.
