MAX547

Octal, 13-Bit Voltage-Output

DAC with Parallel Interface

_______________________________________________________________________________________

3

Note 1:

PSRR is tested by changing the respective supply voltage by ±5%.

Note 2:

For best performance, REF_ should be greater than AGND_ + 2V and less than V

DD

- 0.6V. The device operates with

reference inputs outside this range, but performance may degrade. For further information on the reference, see the
Reference and Analog-Ground Inputs section in the Detailed Description.

Note 3:

Reference input resistance is code dependent. See

Reference and Analog-Ground Inputs section in the Detailed

Description.

Note 4:

Typical settling time with 1000pF capacitive load is 10µs.

Note 5:

Guaranteed by design. Not production tested.

Note 6:

Guaranteed by supply-rejection test.
