All functions of the TSC2007 are working as expected, but the PENIRQ, between interrupts, oscillates. Whether in power down with IRQ enable, or, ADC off with IRQ enable, oscillation is present . The datasheet decoupling recommendation is used at VCC, but also tried a 10uF as seen on the evaluation board. Have tried various pullup values and caps on PENIRQ pin, but the best option appears to be a cap between PENIRQ and VCC. However, still very noisy. Do you have any suggestions to get a cleaner edge on the PENIRQ pin? Thanks, Dan
