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
16вЂ‘/18-bit analog-to-digital converter (ADC) typically
dissipate as much power as the ADC itself, often with
a maximum offset spec of aboutВ 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 В®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
18вЂ‘bit successive approximation register (SAR)ADC.
Operating from a single 5V supply, the LTC2372вЂ‘18
achieves вЂ“110dB THD (typical), 100dB (fully
differential)/95dB (pseudo-differential) SNR (typical) …

1.8V TO 5V 0V 10ВµF 4.096V 91О© + 0V 4300pF The LT6016 is a dual rail-to-rail input op
amp with input offset voltage less than
50ВµV (maximum) that draws only 315Вµ 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 ADCвЂ™s digital
gain compression mode reduces the …
