MAX5853ETL+

The MAX5853ETL+ is a dual, 10bit, 80Msps, current output DAC in 40 pin TQFN package. Device integrates two 10bit DAC cores and a 1.24V reference, the analogue outputs support a -1V to +1.25V compliance voltage. It can also operate in interleave data mode to reduce I/O pin count. This allows converter to be updated on a single 10bit bus. It features digital control of channel gain matching to within ±0.4dB in sixteen 0.05dB steps. Channel matching improves sideband suppression in analogue quadrature modulation applications. The on-chip 1.24V band gap reference includes a control amplifier that allows external full-scale adjustments of both channels through a single resistor. It provides superior dynamic performance in wideband communication systems and used in wireless base stations, quadrature modulation and direct digital synthesis (DDS).

• Supply voltage range is 2.7V to 3.6V, full-scale current outputs of 2mA to 20mA
• Operating temperature range from -40°C to 85°C
• Full output swing and dynamic performance at 2.7V supply
• Superior dynamic performance of 78dBc SFDR at fOUT = 20MHz
• Programmable channel gain matching, low power of 77mW with IFS = 5mA at fCLK = 80MHz
• Integrated 1.24V low noise band gap reference
• Single-resistor gain control
• Interleaved data mode
• Single ended and differential clock input modes
• Internal reference can be disabled, external reference may be applied for high accuracy applications
