AD1864
Key Features
- This results in cophased voltage or current output signals and eliminates the need for output demultiplexing circuitry
- The DACs on the AD1864 chip employ a partially-segmented architecture
- The first four MSBs of each DAC are segmented into 15 elements
- The 14 LSBs are produced using standard R-2R techniques
- Segment and R-2R resistors are lasertrimmed to provide extremely low total harmonic distortion
- When used in the current output mode, the AD1864 provides two cophased ± 1 mA output signals
- Each channel is equipped with a high performance output amplifier
- These amplifiers achieve fast settling and high slew rate, producing ± 3 V signals at load currents up to 8 mA
- Each output amplifier is short-circuit protected and can withstand indefinite short circuits to ground
- The AD1864 was designed to balance two sets of opposing requirements, channel separation and DAC matching
