Key Features
- Dual-output architecture provides both a primary 5 V precision reference and a buffered auxiliary output for powering multiple analog circuits simultaneously
- Low noise spectral density of 4 µV peak-to-peak (0.1 Hz to 10 Hz) ensures clean reference for high-resolution ADCs and precision DACs
- Output voltage accuracy of 4.9975 V to 5.0025 V (±2.5 mV) delivers sub-0.05% initial tolerance without trimming
- High source and sink current capability supports direct load driving without external buffer amplifiers
Applications
The LT6658AHMSE-5#PBF is designed for precision instrumentation, data acquisition systems, and medical measurement equipment where a stable 5 V reference with ultra-low noise is critical for accurate ADC and DAC performance. Its dual-output configuration simplifies powering multiple reference-hungry analog subsystems from a single device, reducing BOM size and board area. Test and measurement instruments, industrial scales, and high-resolution imaging front-ends benefit from its ±2.5 mV accuracy and high-current drive capability.

Frequently Asked Questions
How precise is the 5 V output of the LT6658AHMSE-5#PBF and what does that mean for a 16-bit ADC?
The LT6658AHMSE-5#PBF holds its output voltage between 4.9975 V and 5.0025 V, a tolerance of ±2.5 mV or ±0.05%. For a 16-bit ADC referenced to exactly 5 V, this reference error contributes less than 32 counts of full-scale error out of 65536 possible codes, making it suitable for precision measurement systems without the need for external voltage trimming.
Why does the dual-output design of the LT6658AHMSE-5#PBF benefit multi-channel data acquisition systems?
The dual-output architecture allows one LT6658AHMSE-5#PBF to simultaneously supply a primary reference to an ADC and a secondary reference to a DAC or analog mux, eliminating the need for two separate reference ICs. This reduces BOM cost, board area on a 16-pin SOIC footprint, and the risk of reference-to-reference ground-loop noise that degrades measurement accuracy in densely populated instrumentation boards.
How does the low noise performance of the LT6658AHMSE-5#PBF affect measurement accuracy in a precision weigh scale?
The LT6658AHMSE-5#PBF achieves a noise level of 4 µV peak-to-peak in the 0.1 Hz to 10 Hz band, which directly limits the minimum detectable signal at the ADC input in a weigh scale. At a 5 V reference and 24-bit ADC resolution, this reference noise corresponds to less than 1 count of measurement error, enabling the weigh cell to resolve weight differences down to sub-milligram levels in laboratory balance applications.
