DAC702BH/CH/SH

The DAC702BH/CH/SH belongs to DAC70X family which comprise of complete 16-bit digital-to-analog converters that includes a precision buried-zener voltage reference and a low-noise, fast-settling output operational amplifier (voltage output models), all on one small monolithic chip. And these D/A converters are packaged in hermetic 24-pin ceramic side-brazed or molded plastic. The DIP-pack- aged parts are pin-compatible with the voltage and current output DAC71 and DAC72 model families. Total full-scale gain drift is limited to ±10ppm/°C maximum (LH and CH grades). 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. 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. 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.

The features of DAC702BH/CH/SH can be summarized as (1)VOUT and IOUT models; (2)high accuracy: Linearity Error ±0.0015% of FSR max differential linearity Error ±0.003% of FSR max; (3)monotonic (at 15 bits) over full specification temperature range; (4)pin-compatible with DAC70, DAC71, DAC72; (5)dual-in-line plastic and hermetic ceramic and SOIC.

The absolute maximum ratings of DAC702BH/CH/SH are (1)+VCC to common : 0V, +18V; (2)VCC to common: 0V, 18V; (3)VDD to common: 0V, +18V; (4)digital data inputs to common: 1V, +18V; (5)reference out to common: indefinite short to common; (6)external voltage applied to R F (DAC702): ±18V; (7)external voltage applied to D/A Output (DAC701/703): 5V to +5V; (8)V OUT (DAC701/703): indefinite short to common; (9)power dissipation: 1W; (10)storage temperature: 60°C to +150°C; (11)lead temperature (soldering, 10s): 300°C.
