SINGLE-ENDED INPUT OPERATION
The AD8352 can be configured as a single-ended-to-differential
amplifier, as shown in Figure 26. To balance the outputs when
driving the VIP input, an external resistor (RN) of 200 Ω is added
between VIP and RGN. See Equation 2 to determine the single-
ended input gain (AV Single-Ended) for a given RG or RL.

broadband, third-order, single tone optimization) for 200 Ω and
1 kΩ loads, respectively. This single-ended configuration provides
3 dB bandwidths similar to input differential drive. Figure 28
through Figure 31 show distortion levels at a gain of 12 dB for
both 200 Ω and 1 kΩ loads. Gains from 3 dB to 18 dB, using
optimized CD and RD values, obtain similar distortion levels.
