Frequently Asked Questions
How accurate is the 2.5 V output of the LT6657AHMS8-2.5, and what does that mean for ADC measurements?
The LT6657AHMS8-2.5 guarantees an output voltage between 2.4975 V and 2.5025 V, representing a ±0.05% (±1.25 mV) tolerance. For a 16-bit ADC using this as its reference, a 1.25 mV error corresponds to roughly 3 LSBs, which is negligible for most precision measurement chains and does not require additional trimming.
Can the LT6657AHMS8-2.5 supply current to multiple downstream loads without a buffer?
Yes. The device supports up to 10 mA of output current, allowing it to drive several parallel ADC reference inputs, voltage dividers, or analog front-end circuits simultaneously. This eliminates the need for a separate op-amp output buffer in most designs, reducing component count and board area.
What makes the LT6657AHMS8-2.5 suitable for automotive and medical applications compared with standard commercial references?
The part is specified for automotive and medical use with tight initial accuracy of ±0.05% and a low temperature coefficient, ensuring output stability across a wide temperature range. Its 8-pin MSOP package passes the JESD-609 e3 moisture sensitivity rating, and the AEC-Q100-style qualification supports high-reliability deployments in -40 °C to 125 °C environments such as engine control units and patient monitoring equipment.
