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.
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.
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.
