† All typical values are at VDD = 5 V and TA = 25°C.

NOTES: 20. All monitor output tests are performed with a 10-k

Ω load resistance.

21. Monitor gains are measured with a 1020-Hz, 6-V peak-to-peak sine wave applied differentially between

IN + and IN –.The monitor output gains are nominally 0 dB, – 8 dB, and – 18 dB relative to its input; however,

the output gains are – 6 dB relative to IN + and IN – or AUX IN + and AUX IN –.

22. Squelch is measured differentially with respect to ADC VMID.
