Description

As shown in the functional block diagram below, the TC2411 features a 5-Bit Unary + 9-Bit Binary R2R architecture. 14-bit straight binary data can be input to the DAC at a sample rate of up to 1 GSPS. The DAC provides low-noise and low-spurious performance with digital IF input signals across the first Nyquist band.

The highly linear analog output produced by the TC2411 may be filtered externally to reject the signal image, and is suitable for single-stage upconversion applications.
