Low Power, DC Accurate Drivers for 18-Bit ADCs
Guy Hoover A common misconception about 18-bit SAR ADCs is the only way to drive them
is with a high powered, high speed, low noise op amp or differential driver whose
DC performance often leaves much to be desired. It is possible to use a low
power, DC accurate op amp to drive an 18-bit SAR ADC if the input is a DC or low
bandwidth AC signal and the op amp outputs are given sufficient time to settle.
Using the single-ended to differential driver of Figure 1, four different low power
dual op amps were tested to show the trade-offs in using low power drivers.
This circuit enables the testing of offset voltage, the maximum sample
rate for DC and AC signals, noise and
power consumption. The ADC used
is the LTC2379-18, a 1.6Msps 18-bit
SAR ADC with an offset of В±9LSBs, INL of
В±2LSBs and peak-to-peak noise of 5LSBs.
The four amplifiers used are the
LT1013, LTC6078, LTC6081 precision and
LTC2051HV zero-drift dual op ampsвЂ”
Table 1 shows a summary of their major
specs. The circuit supply voltage is the
voltage applied to the V+ and VвЂ“ terminals
of the op amps. This voltage determines
the power dissipation of the amplifier and
its maximum signal swing. The voltages …
