Electrical specifications are production tested at T
are guaranteed by design and characterization. Typical specifications are at T
DC Performance is tested without load.
Linearity is tested with unloaded outputs to within 20mV of GND and V
Gain and offset calculated from measurements made with V
1016 for MAX5801, and codes 2 and 254 for MAX5800.
Subject to zero and full-scale error limits and V
Measured with the DAC outputs at midscale with one channel transitioning 0 to full scale.
On power-up, the device initiates an internal 200µs (typ) calibration sequence. All commands issued during this time will
be ignored.
