Monolithic 16-Bit DIGITAL-TO-ANALOG CONVERTERS
FEATURES
q VOUT AND IOUT MODELS q HIGH ACCURACY: Linearity Error ±0.0015% of FSR max Differential Linearity Error ±0.003% of FSR max q MONOTONIC (at 15 bits) OVER FULL SPECIFICATION TEMPERATURE RANGE q PIN-COMPATIBLE WITH DAC70, DAC71, DAC72 q DUAL-IN-LINE PLASTIC AND HERMETIC CERAMIC AND SOIC Digital inputs are complementary binary coded and are TTL-, LSTTL-, 54/74C- and 54/74HC-compatible over the entire temperature range. Outputs of 0 to +10V, ±10V, 0 to –2mA, and ±1mA are available. These D/A converters are packaged in hermetic 24-pin ceramic side-brazed or molded plastic. The DIP-packaged parts are pin-compatible with the voltage and current output DAC71 and DAC72 model families. The DAC702 is also pin-compatible with the DAC70 model family. In addition, the DAC703 is offered in a 24-pin SOIC package for surface mount applications.
DESCRIPTION
The DAC70X family comprise of complete 16-bit digital-to-analog converters that includes a precision buried-zener voltage reference and a low-noise, fastsettling output operational amplifier (voltage output models), all on one small monolithic chip. A combination of current-switch design techniques accomplishes not only 15-bit monotonicity over the entire specified temperature range, but also a maximum end-point linearity error of ±0.0015% of full-scale range. Total full-scale gain drift is limited to ±10ppm/°C maximum (LH and CH grades).
