REF_GND (Input) - Ground reference for the internal sampling circuits. Must

be connected to ground.

19

VQ (Output) - Filter connection for internal A/D converter quiescent refer-

ence voltage. A capacitor must be connected from VQ to ground. VQ is not

intended to supply external current. VQ has a typical source impedance of

250 kΩ and any current drawn from this pin will alter device performance.

20

RST (Input) - The device enters a low power mode and all internal registers

are reset to their default settings, including the control port, when low. When

high, the control port becomes operational and the PDN bit must be cleared

before normal operation will occur. The control port cannot be accessed

when Reset is low.
