(see Note D)

NOTES: A. All analog outputs should be buffered if the load is resistive or if the load is capacitive with more than 2-pF loading.

B. When using the TPP and TPM pins to test internal PGA, the AVDD supply voltage should be 3.3 V.

C. Clock signals on the TPP and TPM pins are inverted.

D. These two capacitors should be placed as close to the device as possible.
