Completely self-contained with a stable, low noise, internal zener voltage reference; high-speed current switches; a resistor ladder network; and a low noise output operational amplifier all on a single monolithic chip. The DAC56 operates over a wide power supply range from ±5V to ±12V. Differential linearity error (DLE) is guaranteed to meet specifications without external adjustment. However, provisions for an externally adjustable circuit controlling the MSB error, the differential linearity error at bipolar zero, makes the DLE at BPZ essentially zero and provides for high system performance. The I/V amplifier stage includes an output current limiting circuit to protect both amplifier and load from excessive current. ...
