DAC56

The DAC56 is a complete 16-bit monolithic D/A converter. 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. This assures the user of high system reliability.

A high-speed interface is capable of clocking in data at a rate of 10MHz max, and its interface logic contains a serial data clock (input), serial data (input) and latch-enable (input). Serial data is clocked MSB first into a 16-bit register and then latched into a 16-bit parallel register.

The DAC56 is packaged in a 16-pin plastic DIP and 16-pin SOIC.
