Part Number: DAC5662A

Function: DUAL, 12-BIT 275 MSPS DIGITAL-TO-ANALOG CONVERTER

Package: 48-Pin Thin-Quad Flat Pack (TQFP) Type

Manufacturer: Texas Instruments

Description

The DAC5662 is a monolithic, dual-channel 12-bit high-speed digital-to-analog converter (DAC) with on-chipvoltage reference. Operating with update rates of up to 275 MSPS, the DAC5662A offers exceptional dynamic performance and tight-gain and offset matching, characteristics that make it suitable in either I/Q baseband or direct IF communication applications.
Each DAC has a high-impedance differential current output, suitable for single-ended or differential analog-output configurations. External resistors allow scaling the full-scale output current for each DAC separately or together, typically between 2 mA and 20 mA. An accurate on-chip voltage reference is temperature compensated and delivers a stable 1.2-V reference voltage. Optionally, an external reference may be used.

The DAC5662A has two 12-bit parallel input ports with separate clocks and data latches. For flexibility, the IC also supports multiplexed data for each DAC on one port when operating in the interleaved mode.The DAC5662 has been specifically designed for a differential transformer coupled output with a 50-Ω doubly terminated load. For a 20-mA full-scale output current a 4:1 impedance ratio (resulting in an output power of 4 dBm) and 1:1 impedance ratio transformer (-2 dBm output power) are supported. The device is available in a 48-pin thin quad FlatPack (TQFP). Pin compatibility between family members provides 12-bit (DAC5662A) and 14-bit (DAC5672) resolution. Furthermore, the DAC5662A is pin compatible to the DAC2902 and AD9765 dual DACs. The device is characterized for operation over the industrial temperature range of -40°C to 85°C.
