DAC1201D125

Dual 12-bit DAC, up to 125 Msps

Rev. 03 — 2 July 2012

Product data sheet

1. General description

The DAC1201D125 is a dual-port, high-speed, 2-channel CMOS Digital-to-Analog

Converter (DAC), optimized for high dynamic performance with low power dissipation.

Supporting an update rate of up to 125 Msps, the DAC1201D125 is suitable for Direct IF

applications.

Separate write inputs allow data to be written to the two DAC ports independently of one

another. Two separate clocks control the update rate of each DAC port.

The DAC1201D125 can interface two separate data ports or one single interleaved

high-speed data port. In Interleaved mode, the input data stream is demultiplexed into its

original I and Q data and latched. The I and Q data is then converted by the two DACs

and updated at half the input data rate.

Each DAC port has a high-impedance differential current output, suitable for both

single-ended and differential analog output configurations.

The DAC1201D125 is pin compatible with the AD9765, DAC2902 and DAC5662.
