AD768ARZ

The AD768ARZ is a kind of 16-bit, high speed digital-to-analog converter(DAC) and it offers exceptional ac and dc performance. It is manufactured on ADI's Advanced Bipolar CMOS(ABCMOS) process, combining the speed of bipolar transistors,the accuracy of laser-trimmable thin film resistors, and the efficiency of CMOS logic.

Features of the AD768ARZ are:(1)30 MSPS update rate; (2)16-bit resolution; (3)fast settling: 25 ns full-scale settling to 0.025%; (4)SFDR @ 1 MHz output: 86 dBc; (5)THD @ 1 MHz output: 71 dBc; (6)low glitch impulse: 35 pV-s; (7)power dissipation: 465 mW; (8)on-chip 2.5 V reference; (9)edge-triggered latches; (10)multiplying reference capability.

The absolute maximum ratings of the AD768ARZ can be summarized as:(1): positive supply voltage (VDD,with respect to DCOM, REFCOM, LADCOM) is 0.5 V min and +6.0 V max; (2): negative supply voltage (VEE,with respect to DCOM, REFCOM, LADCOM) is 6.0 V min and  +0.5 V max; (3): analog-to-other grounds (REFCOM,with respect to DCOM, LADCOM) is 0.5 V min and +0.5 V max; (4): digital-to-other grounds (DCOM,with respect to LADCOM, REFCOM) is 0.5 V min and +0.5 V max; (5): reference output (REFOUT,with respect to REFCOM) is VDD + 0.5 V max; (6): reference input current (IREFIN) is +7.5 mA max; (7): digital inputs (DB0DB15, CLOCK,with respect to DCOM) is 0.5 V min and VDD + 0.5 V max; (8): analog outputs (IOUTA, IOUTB, with respect to LADCOM) is 2.0 V min and +5.0 V max; (9): maximum junction temperature is +150 °C max; (10): storage temperature is 65 °C min and +150 °C max; (11): lead temperature is +300 °C max.
