Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The AD7549JNZ is a single-chip, dual-channel, 12-Bit current output DAC. It adopts a 20-pin DIP package. Both Dacs offer four-quadrant multiplication functionality, and each DAC has a separate reference voltage input and feedback resistor. The single-chip structure can ensure excellent heat dissipation tracking and gain error tracking characteristics between the two Dacs.
