    Low Power, Precision Op Amp Simplifies
    Driving of MUXed ADCs
    Design Note 1034
    Guy Hoover
    Introduction
    The high speed op amps required to buffer a modern
    16‑/18-bit analog-to-digital converter (ADC) typically
    dissipate as much power as the ADC itself, often with
    a maximum offset spec of about 1mV, well beyond
    that of the ADC. If multiple multichannel ADCs are
    required, the power dissipation can quickly rise to
    unacceptable levels.
    The simple buffer presented here is capable of driving
    the LTC ®2372-18 8-channel ADC and achieving near
    data sheet SNR, THD and offset performance with very
    low power dissipation if the input signals involved are
    in the range of DC to 1kHz.
    Circuit Description
    The LTC2372-18 is a low noise, 500ksps, 8-channel
    18‑bit successive approximation register (SAR)ADC.
    Operating from a single 5V supply, the LTC2372‑18
    achieves –110dB THD (typical), 100dB (fully
    differential)/95dB (pseudo-differential) SNR (typical) ...

    1.8V TO 5V 0V 10µF 4.096V 91Ω + 0V 4300pF The LT6016 is a dual rail-to-rail input op
    amp with input offset voltage less than
    50µV (maximum) that draws only 315µ A
    per amplifier (typical). It is also available
    as a single and a quad (LT6015/LT6017).
    The circuit of Figure 1 shows the LT6016
    op amp configured as a noninverting
    buffer driving the analog inputs of the
    LTC2372-18. Typical power dissipation
    of each op amp is only 3.7mW. For all
    eight channels, this is a power dissipation of only 30mW, approximately the
    same power dissipation as the ADC.
    Running the LT6016 on a single 5.25V
    supply and enabling the ADC’s digital
    gain compression mode reduces the ...
