Device Functional Modes

The THP210 requires external resistors for correct signal-path operation. When setting the gain with these external resistors, the amplifier can be either on with the PD pin left floating, asserted to a voltage greater than VVS+ – 0.5 V, or turned off by forcing PD to a voltage lower than VVS+ – 2 V. Disabling the amplifier shuts off the quiescent current and stops correct amplifier operation. The signal path is still present for the source signal through the external resistors, which provides poor signal isolation from the input to output in power-down mode.

Internal protection diodes remain present across the input pins in both operating and shutdown mode. Large input signals during disable can turn on the input differential protection diodes, thus producing a load current in the supply, even in shutdown.

The VOCM control pin sets the output average voltage. Left open, VOCM defaults to an internal midsupply value. Driving this high-impedance input with a voltage reference within the valid range sets a target for the internal VCM error amplifier. If floated to obtain a default midsupply reference for VOCM, an external decoupling capacitor must be added on the VOCM pin to reduce the otherwise high output noise for the internal high-impedance bias.
