DAC5662
SLAS425B – JULY 2004 – REVISED MAY 2007 ................................................................................................................................................................ www.ti.com
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 DAC5662 is available in a 48-pin thin quad FlatPack (TQFP). Pin compatibility between family members
provides 12-bit (DAC5662) and 14-bit (DAC5672) resolution. Furthermore, the DAC5662 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.
