Frequently Asked Questions
What SNR and INL does LTC2377IMS-20#PBF achieve, and why do these matter for precision measurement systems?
LTC2377IMS-20#PBF achieves 104 dB SNR and 0.5 ppm INL. A 104 dB SNR means the signal is over 100,000 times stronger than the noise floor, and 0.5 ppm INL ensures the transfer function deviates by less than half a part per million across the full input range, making it suitable for high-accuracy weighing, pressure, and temperature measurement.
How does the 500 ksps sample rate of LTC2377IMS-20#PBF compare to slower 24-bit ADCs for industrial data acquisition?
At 500 ksps, LTC2377IMS-20#PBF samples 500,000 times per second, compared to typical 24-bit sigma-delta ADCs operating at 10 to 100 ksps. This 5 to 50 times speed advantage allows capturing faster transients in vibration analysis, power quality monitoring, and multi-channel scanning without aliasing at 20-bit resolution.
What is the analog input voltage range of LTC2377IMS-20#PBF, and how does it interface with bipolar sensor signals?
LTC2377IMS-20#PBF accepts analog inputs from -2.5 V to 5.1 V, covering a 7.6 V total span that accommodates bipolar sensor outputs without additional level shifting. This allows direct connection to ±2.5 V bridge sensor amplifiers and differential signal sources in industrial measurement front-ends.
How much power does LTC2377IMS-20#PBF consume, and is it practical for multi-channel ADC arrays in power-constrained designs?
LTC2377IMS-20#PBF consumes only 10.5 mW during active conversion. In an 8-channel array, total ADC power would be approximately 84 mW, which is manageable in rack-mount instrumentation or portable data recorders running on battery power, especially compared to higher-speed 20-bit converters that can exceed 50 mW per channel.
