design features The Refulator: Precision Voltage Reference is an Accurate
Low Noise Regulator for 200mA Loads
Michael B. Anderson Precision analog designers often lean on the quietly humble voltage reference to
power their DAC and ADC converters. This job lies outside the fundamental purview
of a referenceвЂ”ostensibly designed to provide a clean, precise stable voltage to an
actual power source, namely a power converterвЂ™s reference input. With some caveats,
references are usually up to the task, emboldening designers to ask references to
power increasingly higher current applications. After all, if the reference can power the
converter, why not the analog signal chain, or another converter, and on down the list?
The choice between precision and power
comes up often in any design process.
The brute force approach to making
this decision suggests using a reference
when precision is demanded, and an LDO
when milliwatts of power are required.
Besides the additional board space and
cost, separate signals must be routed, even
if their nominal voltages are the same.
And, if a high precision voltage source is
required to provide milliwatts of power,
the designer is forced to buffer a reference.
The LT6658 solves this dilemma by
providing two low noise precision outputs …
