Frequently Asked Questions
What is the output voltage accuracy of the LT6657AHMS8-5#PBF and how does it affect ADC full-scale error?
The LT6657AHMS8-5#PBF guarantees an output voltage between 4.995 V and 5.005 V, representing a ±1 mV or ±0.02% initial accuracy. For a 16-bit ADC with a 5 V full-scale range, this 1 mV reference error contributes approximately 0.65 LSB of gain error, which is within the acceptable range for most precision measurement and automotive sensor digitization applications.
How much output current can the LT6657AHMS8-5#PBF supply and can it directly drive multiple ADC reference inputs?
The LT6657AHMS8-5#PBF sources up to 10 mA output current, which is sufficient to simultaneously drive the reference inputs of several 16-bit ADCs that typically draw 1 mA to 3 mA each. This eliminates the need for an external op amp buffer in most multi-channel data acquisition systems, reducing BOM cost and simplifying PCB layout.
Why is the LT6657AHMS8-5#PBF preferred over a band-gap reference from a general-purpose regulator in automotive ECU designs?
The LT6657AHMS8-5#PBF is AEC-Q100 qualified and specifies ±1 mV accuracy across the full -40°C to 125°C automotive temperature range, while general-purpose regulator outputs typically drift by several tens of millivolts with temperature. This tight 5 V precision is essential for powertrain sensor ADC references in engine control units where a 10 mV reference shift would cause measurable fuel injection or ignition timing errors.
