HI5660
8-Bit, 125/60MSPS, High Speed D/A
Converter
The HI5660 is an 8-bit, 125MSPS, high speed, low power,
D/A converter which is implemented in an advanced CMOS
process. Operating from a single +3V to +5V supply, the
converter provides 20mA of full scale output current and
includes edge-triggered CMOS input data latches. Low glitch
energy and excellent frequency domain performance are
achieved using a segmented current source architecture. For
an equivalent performance dual version, see the HI5628.
This device complements the CommLinkTM HI5X60 family of
high speed converters offered by Intersil, which includes 8,
10, 12, and 14-bit devices.

NOTES:
2. Gain Error measured as the error in the ratio between the full scale output current and the current through R
SET
(typically 625
A). Ideally the
ratio should be 32.
3. Parameter guaranteed by design or characterization and not production tested.
4. Spectral measurements made with differential transformer coupled output and no external filtering.
5. Measured with the clock at 50MSPS and the output frequency at 1MHz.
6. Measured with the clock at 100MSPS and the output frequency at 40MHz.
7. See `Definition of Specifications'.
8. It is recommended that the output current be reduced to 12mA or less to maintain optimum performance for operation below 3V. DV
DD
and
AV
DD
do not have to be equal.
9. For operation above 125MHz, it is recommended that the power supply be 3.3V or greater. The part is functional with the clock above 125MSPS
and the power supply below 3.3V, but performance is degraded.
10. Measured with the clock at 60MSPS and the output frequency at 10MHz.
