7 / 18 page REV. 0 AD5303/AD5313/AD5323 –7– MAJOR-CODE TRANSITION GLITCH ENERGY Major-code transition glitch energy is the energy of the impulse injected into the analog output when the code in the DAC regis- ter changes state. It is normally specified as the area of the glitch in nV-secs and is measured when the digital code is changed by 1 LSB at the major carry transition (011 . . . 11 to 100 . . . 00 or 100 . . . 00 to 011 . . . 11). DIGITAL FEEDTHROUGH Digital feedthrough is a measure of the impulse injected into the analog output of the DAC from the digital input pins of the device, but is measured when the DAC is not being written to (SYNC held high). It is specified in nV secs and is measured with a full-scale change on the digital input pins, i.e., from all 0s to all 1s and vice versa. ANALOG CROSSTALK This is the glitch impulse transferred to the output of one DAC due to a change in the output of the other DAC. It is measured by loading one of the input registers with a full-scale code change (all 0s to all 1s and vice versa) while keeping LDAC high. Then pulse LDAC low and monitor the output of the DAC whose digital code was not changed. The area of the glitch is expressed in nV-secs. DAC-TO-DAC CROSSTALK This is the glitch impulse transferred to the output of one DAC due to a digital code change and subsequent output change of the other DAC. This includes both digital and analog crosstalk. It is measured by loading one of the DACs with a full-scale code change (all 0s to all 1s and vice versa) while keeping LDAC low and monitoring the output of the other DAC. The area of the glitch is expressed in nV-secs. DC CROSSTALK This is the dc change in the output level of one DAC in re- sponse to a change in the output of the other DAC. It is mea- sured with a full-scale output change on one DAC while monitoring the other DAC. It is expressed in µV. POWER SUPPLY REJECTION RATIO (PSRR) This indicates how the output of the DAC is affected by changes in the supply voltage. PSRR is the ratio of the change in VOUT to a change in VDD for full-scale output of the DAC. It is measured in dBs. VREF is held at +2 V and VDD is varied ±10%. REFERENCE FEEDTHROUGH This is the ratio of the amplitude of the signal at the DAC out- put to the reference input when the DAC output is not being updated (i.e., LDAC is high). It is expressed in dBs. TOTAL HARMONIC DISTORTION This is the difference between an ideal sine wave and its attenu- ated version using the DAC. The sine wave is used as the refer- ence for the DAC and the THD is a measure of the harmonics present on the DAC output. It is measured in dBs. MULTIPLYING BANDWIDTH The amplifiers within the DAC have a finite bandwidth. The multiplying bandwidth is a measure of this. A sine wave on the reference (with full-scale code loaded to the DAC) appears on the output. The multiplying bandwidth is the frequency at which the output amplitude falls to 3 dB below the input. CHANNEL-TO-CHANNEL ISOLATION This is a ratio of the amplitude of the signal at the output of one DAC to a sine wave on the reference input of the other DAC. It is measured in dBs.
