| 6/23/04 Errata: CS5371/72 Rev D Errata (Reference CS5371/CS5372 data sheet revision DS255PP2 dated APR '01) Erratum #1: THD for 5% tolerance unipolar power supplies. Description: Characterization testing shows degraded total harmonic distortion performance for certain unipolar power supply conditions. Modulator does not meet -112 dB maximum THD performance for the following power supply configurations: Test Conditions -5% Unipolar Analog / -5% Digital -5% Unipolar Analog / +5% Digital +5% Unipolar Analog / -5% Digital +5% Unipolar Analog / +5% Digital VA+ +4.75 V +4.75 V +5.25 V +5.25 V VA0V 0V 0V 0V VD +3.135 V +5.25 V +3.135 V +5.25 V Max THD -100 dB -100 dB -100 dB -100 dB Work Around: Use a nominal +5.00 V analog power supply in unipolar configuration to achieve data sheet performance. Erratum #2: Anti-alias filter components. Description: The data sheet specifies a single pole anti-alias filter in front of the modulator differential inputs using 1 k series resistors and differential 10 nF capacitors. Characterization testing shows better performance using 20 nF differential capacitors. Work Around: Discrete - use external 500 series resistors and 20 nF differential capacitors. CS3301/02 - use the internal 750 series resistors, plus external 0 series resistors and 20 nF differential capacitors. External resistors can be populated when using CS3301A, which removes the internal 750 series resistors.

Description: When set high, the OFST pin adds differential offset to the modulator inputs to move any idle tones out of the measurement bandwidth. The data sheet specifies +100 mV offset will be added, but actually -50 mV offset is added. Work Around: None. CS5371/72 rev E will increase the differential offset added by the OFST pin to -100 mV. Erratum #4: Voltage reference RC filters. Description: In multi-channel systems it is common to share a single precision voltage reference between multiple modulators and DACs. To avoid interactions between devices through their voltage reference inputs, independent low-pass RC filters should be placed between the voltage reference and the VREF inputs of each device. Work Around: Use a separate RC low-pass filter (as recommended by the voltage reference manufacturer) in front of each voltage reference input. 2 ER255A3 |
