Precision Op Amp Enables Fast Multiplexing at Low Power
Design Note 536
Kris Lokere
Introduction
If you are designing a system that measures a number
of analog voltages, but not all at the same time, you
can reduce downstream circuitry by multiplexing the
measurements into a single output signal, then serially
process and digitize the original voltage levels using
shared components. The benefit is that the number
and size of signal chain components is a fraction of
that required by a per-channel design. Properly implementing a multiplexing solution requires attention to
a few details, especially if you want to quickly switch
between channels, measure accurately and maintain
low power consumption.
Respond Quickly
Multiplexing increases the frequency content of the
combined signal, since every time the multiplexer
switches channels, the multiplexed signal changes
value. Even if the input signals do not change quickly,
the multiplexed signal does, so any circuitry after the
multiplexer must respond quickly to these transitions.
For instance, if the output signal does not fully settle …

Micropower Op Amp Drives 8-Channel 18-Bit Simultaneous Sampling ADC without Compromising Accuracy or Breaking the Power Budget &mdash DN541

Micropower Op Amp Drives 8-Channel 18-Bit Simultaneous
Sampling ADC without Compromising Accuracy or Breaking
the Power Budget
Design Note 541
Guy Hoover
Introduction
The op amps used to drive 18-bit analog-to-digital
converters (ADCs) typically draw as much supply
current as the ADC itself, often with a maximum offset
spec that is well above that of the ADC. If multiple ADC
channels are required, the power dissipation from these
drivers quickly rises to unacceptable levels. consumption drops to 45mW (typical) by using the
deviceвЂ™s NAP mode.
The LT6020 is a dual micropower, 5V/Вµs precision
rail-to-rail output op amp with input offset voltage of
less than 30ВµV (maximum) that draws only 100ВµA per
amplifier (maximum).
The circuit of Figure 1 shows the LT6020 op amp
configured as a noninverting buffer driving the analog
inputs of the LTC2348-18. Maximum power dissipation
of each op amp is only 3mW. For all eight channels
this adds up to only 24mW, approximately half the
ADC power consumption at 10ksps. If 18-bit precision is required (SNR, THD, VOS), but …
