DESCRIPTION

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. How-

ever, provisions for an externally adjustable circuit

controlling the MSB error, the differential linearity

error at bipolar zero, makes the DLE at BPZ essen-

tially 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 con-

tains 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.
