AD9146 is a dual-channel, 16-bit, 1230 MSPS, TxDAC+ digital-to-analog converter.
The AD9146 is a dual, 16‑bit, high‑dynamic‑range digital‑to‑analog converter (DAC) that provides a nominal sample rate of 1000 MSPS and up to 1230 MSPS with increased supplies. It features a flexible LVDS interface, programmable output current (8.66 mA to 31.66 mA), and integrated interpolation and complex modulation for direct‑conversion transmit applications.
The device includes extensive synchronization options, low‑power operation (as low as 780 mW at 500 MSPS with PLL off), and a 48‑lead LFCSP package with an exposed pad for thermal management. Detailed specifications cover DC, digital, AC performance, pin functions, and timing requirements for LVDS, serial port, and clock interfaces.
| Resolution | 16 Bits |
|---|---|
| Full‑Scale Output Current | 8.66 mA – 31.66 mA |
| Maximum Sample Rate | 1230 MSPS (with increased supplies) |
| Power Consumption (2× mode, 500 MSPS) | 780 mW (PLL off) |
The AD9146 can sample at up to 1230 MSPS when supplied with increased voltages.
The full‑scale output current can be programmed from 8.66 mA to 31.66 mA.
In 2× mode at 500 MSPS with the PLL off, the device consumes about 780 mW.
