bipolar DACsTexas Instruments introduced a four-channel, high-voltage, bipolar digital-to-analog converter (DAC) for ATE and medical equipment design. The DAC8734 features drift characteristics of 2 ppm over 500 hours; 3 ppm over 1000 hours, and it comes in a 6 mm x 6 mm QFN-40 or 7 mm x 7 mm TQFP-48 package. The device is capable of driving ±16 V or 0 to +20 V across four channels, eliminating the external operational amplifier typically required for additional voltage gain. Designers need to add only a single voltage reference for bipolar operation.
