DESCRIPTION

The 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 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 a 16-pin plastic DIP and 16-pin SOIC.

NOTES: (1) Logic input levels are TTL-/CMOS-compatible. (2) FSR means full-scale range and is equivalent 6V (�3V) for DAC56 in the VOUT mode. (3) Measured with an active clamp to provide a low impedance for approximately 200ns. (4) All specifications assume +VS connected to +VL and �VS connected to �VL. If supplies are connected separately, �VL must not be more negative than �VS to assure proper operation. No similar restriction applies to the value of +VL with respect to +VS.
