The MAX5858A is a dual, 10-bit, 300Msps digital-to-analog converter (DAC) from Texas Instruments that provides superior dynamic performance in wideband communication systems. The MAX5858A integrates two 10-bit DAC cores, 4x/2x/1x programmable digital interpolation filters, phase-lock loop (PLL) clock multiplier, and a 1.24V reference. The MAX5858A sup- ports single-ended and differential modes of operation. The MAX5858A dynamic performance is maintained over the entire power-supply operating range of 2.7V to 3.3V. The analog outputs support a compliance voltage of -1.0V to +1.25V. The 4x/2x/1x programmable interpolation filters feature excellent passband distortion and noise performance. Interpolating filters minimize the design complexity of analog reconstruction filters while lowering the data bus and the clock speeds of the digital interface. The PLL multiplier generates all internal, synchronized high- speed clock signals for interpolating filter operation and DAC core conversion. The internal PLL helps minimize system complexity and lower cost. To reduce the I/O pin count, the DAC can also operate in interleave data mode. This allows the MAX5858A to be updated on a single 10-bit bus. The MAX5858A features digital control of channel gain matching to within ±0.4dB in sixteen 0.05dB steps. Channel matching improves sideband suppression in analog quadrature modulation applications. The on- chip 1.24V bandgap reference includes a control amplifier that allows external full-scale adjustmen
The MAX5858A dual, 10‑bit, 300 Msps digital‑to‑analog converter provides high‑speed conversion for wideband communication systems. It integrates two DAC cores, programmable 4×/2×/1× interpolation filters, an internal PLL multiplier and a 1.24 V band‑gap reference. The device operates from a single 2.7 V‑3.3 V supply and supports both single‑ended and differential output modes.
The DAC offers full‑scale output currents of 2 mA to 20 mA, output voltage compliance from –1.0 V to +1.25 V, and three power‑control modes (normal, low‑power standby, power‑down). It is supplied in a 48‑pin TQFP‑EP package and is rated for –40 °C to +85 °C operation, making it suitable for communications, satellite links, direct‑digital synthesis and instrumentation applications.
