Generating a В±10.24V True Bipolar Input for an 18-Bit, 1Msps
SAR ADC
Design Note 522

Introduction
The LTC В®2338 is an 18-bit fully differential SAR ADC
that is remarkably easy to drive. This 1Msps ADC operates from a single 5V supply and achieves В±4LSB INL
maximum with вЂ“111dB THD and 100dB SNR. Its fully
differential В±20.48V true bipolar input range minimizes
the need for range scaling, and its 2kО© resistive input
greatly reduces the charge kickback from the internal
sampling capacitor.
ADCs claiming similar performance require scaling
to exceed what is typically a 0V to VREF input range,
resulting in low impedance inputs or an additional
buffer stage requirement. To band limit noise and
minimize disturbances reflected into the buffer from
sampling transients, other ADCs require filter circuitry
composed of expensive film or C0G capacitors at the
driver output. In contrast, the simple driver circuit
presented here requires only a dual precision op amp
and two resistors to drive the LTC2338-18. Layout
strategies for this circuit are also shown. C59 …
