Errata: CS3302 Rev C Errata (Reference CS3302 data sheet revision DS596F3 dated DEC ’07) Erratum #1: Integrated anti-alias filter resistor tolerance. Description: The integrated anti-alias filter resistors are specified as 750 Ω ±30%. However, this full tolerance results in a variable phase delay between channels of a synchronous system. Work Around: Short Term - Resistor test limits tightened to 605 Ω ±6% @ -40°C and 675 Ω ±5% @ 85°C. Long Term - New CS3302A device removes internal resistors and requires external resistors. Erratum #2: Relative gain accuracy. Description: Relative gain accuracy specified as ±0.4% typical, ±0.8% max. Many acquisition systems require better relative gain accuracy. Work Around: Production test limits tightened to ±0.2% max. Erratum #3: Voltage noise test limit in 0.1 Hz - 10 Hz bandwidth. Description: Low-frequency noise specified as 1 µV peak-to-peak typical, 1.5 µV peak-to-peak max. Statistical variability of the low-frequency noise measurement requires an increased max test specification. Work Around: Production test limit increased to 3 µV peak-to-peak max. 1 µV peak-to-peak typical specification is not affected.
