The input stage supports input voltages below ground and to within 1.7V of the positive supply.

The offset matching between inputs makes this an attractive input stage for this application. The differential-to-single-ended gain for this circuit is 2.0V/V.

OPA3832 www.ti.com ............................................................................................................................................ SBOS370A – DECEMBER 2006 – REVISED AUGUST 2008 MULTIPLEXED CONVERTER DRIVER The output resistors isolate the outputs from each other when switching between channels. The feedback network of the disabled channels forms part of the load seen by the enabled amplifier, attenuating the signal slightly.

OPA3832 SBOS370A – DECEMBER 2006 – REVISED AUGUST 2008 ............................................................................................................................................ www.ti.com LOW-PASS FILTER The circuit in Figure 54 realizes a 7th-order Butterworth low-pass filter with a –3dB bandwidth of 2MHz. This filter is based on the KRC active filter topology that uses an amplifier with the fixed gain ≥ 1. The OPA3832 makes a good amplifier for this type of filter.

OPA3832 www.ti.com ............................................................................................................................................ SBOS370A – DECEMBER 2006 – REVISED AUGUST 2008 DESIGN-IN TOOLS DEMONSTRATION FIXTURES Two printed circuit boards (PCBs) are available to assist in the initial evaluation of circuit performance using the OPA3832 in its two package options. Both of these are offered free of charge as unpopulated PCBs, delivered with a user's guide.

Relative to alternative solutions, it provides exceptional performance into lighter loads and/or operating on a single +3.3V supply.

OPA3832 www.ti.com ............................................................................................................................................ SBOS370A – DECEMBER 2006 – REVISED AUGUST 2008 A fine-scale output offset null, or dc operating point adjustment, is often required. Numerous techniques are available for introducing dc offset control into an op amp circuit. Most of these techniques are based on adding a dc current through the feedback resistor.

For short connections, consider the trace and the input to the next device as a lumped capacitive load.
