Frequently Asked Questions
How many channels does the LTC2495CUHF#PBF support and how are they configured?
The LTC2495CUHF#PBF supports 16 single-ended or 8 fully differential analog input channels, selectable via the I2C command word. This flexibility lets designers handle up to 16 independent sensor signals at 16-bit resolution without external multiplexers, simplifying board layout and reducing component count.
What is the maximum conversion rate and how does it handle power-line noise rejection?
The LTC2495 achieves a maximum conversion time of approximately 163.5 ms per reading. Its delta-sigma architecture provides simultaneous rejection of both 50 Hz and 60 Hz interference, making it suitable for industrial environments where mains-frequency noise would otherwise corrupt 16-bit resolution measurements.
When would the LTC2495CUHF#PBF be preferred over a simpler 12-bit ADC for a sensor interface design?
When the application demands better than 0.01% measurement accuracy across the full scale, the LTC2495's 16-bit resolution and 0.002% linearity error deliver performance that 12-bit converters cannot match. Applications such as precision weigh scales, RTD temperature measurement at ±0.5°C, and bridge-sensor conditioning benefit from the integrated 256x PGA and on-chip temperature compensation.
What supply voltage range does the LTC2495CUHF#PBF require for operation?
The LTC2495CUHF#PBF operates from a 2.7 V to 5.5 V single supply, making it compatible with both 3.3 V and 5 V digital systems. This wide supply range simplifies power design in mixed-voltage industrial boards and battery-powered field instruments requiring long-life low-voltage operation.
