What are the key features of LT6657BHMS8-2.5#PBF?

Ultra-low temperature coefficient of 3 ppm/°C maximum, maintaining 2.5 V output stability across -40°C to 125°C
Buffered output capable of sourcing and sinking 50 mA, directly driving ADC reference inputs without additional buffer stages
Low output noise of 4 µVRMS (10 Hz to 10 kHz) for high-resolution ADC and DAC applications requiring clean reference voltage
High initial accuracy of ±0.1% (±2.5 mV) at 2.5 V output voltage, reducing system calibration overhead
Wide input supply range of 2.7 V to 13.2 V with reverse-input protection for versatile power supply compatibility

What is LT6657BHMS8-2.5#PBF used for?

The LT6657BHMS8-2.5 is used as a precision 2.5 V reference in 16-bit and 18-bit ADC and DAC circuits where temperature drift above 3 ppm/°C would degrade measurement accuracy. Industrial data acquisition systems, precision instrumentation amplifiers, and strain-gauge bridge conditioners rely on its 50 mA buffered output to supply multiple parallel ADC reference inputs without droop. Its low noise floor of 4 µVRMS also makes it suitable for audio DAC reference rails and high-accuracy calibration equipment operating across the full -40°C to 125°C industrial temperature range.

Frequently Asked Questions

What is the temperature coefficient of the LT6657BHMS8-2.5 and why does it matter for precision ADCs?

The LT6657BHMS8-2.5 specifies a maximum temperature coefficient of 3 ppm/°C, meaning the 2.5 V output drifts no more than 7.5 µV per degree Celsius. For a 16-bit ADC with a 2.5 V reference, one LSB equals 38 µV, so the reference adds less than one-quarter LSB of error per 5°C change, preserving measurement accuracy in industrial temperature ranges from -40°C to 125°C.

How much output current can the LT6657BHMS8-2.5 source and is it sufficient to drive multiple ADC inputs?

The LT6657BHMS8-2.5 can source up to 50 mA from its buffered output, which is enough to simultaneously drive several high-speed ADC reference pins that each draw 5 mA to 10 mA. The buffered architecture maintains tight 2.5 V regulation under load transients, making it a better choice than unbuffered bandgap references in multi-channel data acquisition boards.

What supply voltage range does the LT6657BHMS8-2.5 accept and how does that affect system design?

The LT6657BHMS8-2.5 accepts input supply voltages from 2.7 V to 13.2 V, accommodating both 3.3 V and 5 V logic supply rails as well as unregulated 12 V automotive or industrial power buses. This wide input range eliminates the need for a separate pre-regulator in many 2.5 V reference designs, simplifying the overall analog power supply architecture.

How does the output noise of the LT6657BHMS8-2.5 compare to typical bandgap references in audio DAC designs?

The LT6657BHMS8-2.5 delivers output noise of 4 µVRMS from 10 Hz to 10 kHz, which is 3 to 5 times lower than a standard unbuffered bandgap reference in the same supply range. For a 24-bit audio DAC using a 2.5 V reference, this low noise floor prevents reference noise from limiting dynamic range, helping achieve signal-to-noise ratios above 110 dB in high-fidelity audio systems.
