NOTES

¹Operating temperature range is as follows: B Version, –40°C to +85°C.

²100% production tested.

³f_MCLK= 6.25 MHz, Frequency Word = 5671C71C HEX, f_OUT= 2.11 MHz.

⁴See Figure 11. To reduce the wake-up time at low power supplies and low temperature, the use of an external reference is suggested.

⁵Measured with the digital inputs static and equal to 0 V or DVDD.

The AD9832 is tested with a capacitive load of 50 pF. The part can be operated with higher capacitive loads, but the magnitude of the analog output will be attenuated.

For example, a 5 MHz output signal will be attenuated by 3 dB when the load capacitance equals 85 pF.

Specifications subject to change without notice.
