Frequently Asked Questions
What is the temperature coefficient of the LT6657BHMS8-2.5, and why does it matter for precision ADC designs?
The LT6657BHMS8-2.5 has a maximum temperature coefficient of 3 ppm/°C, meaning the 2.5V reference shifts by no more than 7.5 µV per degree Celsius. For a 16-bit ADC with 2.5V full-scale, this drift represents less than 0.5 LSB over a 10°C temperature change, preserving measurement accuracy across the operating range.
Can the LT6657B output drive an ADC reference pin directly without an external buffer?
Yes, the LT6657B includes an integrated output buffer capable of sourcing and sinking load currents, allowing it to drive ADC reference pins directly without an external buffer amplifier. This eliminates additional components and reduces board area, particularly valuable in compact 8-pin MSOP designs for portable instruments.
How accurate is the initial output voltage of the LT6657BHMS8-2.5 at room temperature?
The LT6657BHMS8-2.5 guarantees an output voltage between 2.4975V and 2.5025V at room temperature, representing ±0.1% initial accuracy or ±2.5 mV maximum deviation. This level of precision is suitable for 12-bit to 14-bit ADC applications without requiring output trimming or calibration at production test.
In what measurement applications is the LT6657BHMS8-2.5 most commonly deployed?
The LT6657BHMS8-2.5 is commonly used in precision data acquisition boards, industrial process controllers, medical instrumentation, and weigh-scale systems where a stable 2.5V reference supports 12-bit to 16-bit converters. Its low noise and 3 ppm/°C drift maintain sub-LSB reference stability over the -40°C to +85°C industrial temperature range.
What input supply voltage range does the LT6657B require to maintain its 2.5V regulated output?
The LT6657B requires an input supply voltage of at least 0.5V above its 2.5V output, typically 3.0V to 5.5V input range. This dropout headroom allows operation from 3.3V or 5V system rails commonly used in industrial data acquisition hardware without a separate dedicated reference supply.
