What are the key features of LTC2385IUH-18#PBF?
- 18-bit resolution with 5 Msps sample rate and 0.0015% maximum linearity error suits precision data acquisition at high throughput
- Successive approximation register (SAR) architecture with 0.31 µs maximum conversion time supports deterministic low-latency control loops
- Differential analog input range of -4.076 V to +4.116 V (approximately 8.2 V span) enables direct interface with wide-range sensor outputs without signal conditioning
What is LTC2385IUH-18#PBF used for?
The LTC2385IUH-18#PBF is used in precision test-and-measurement instruments, medical imaging systems, and industrial process controllers where 18-bit resolution at 5 Msps is required to digitize fast-changing analog signals with sub-millivolt accuracy. Its wide differential input range and low linearity error make it well suited for current and voltage sensing in power conversion monitors and scientific data loggers. The QFN-48 package enables compact board designs in radar receivers and software-defined radio front-ends that demand high dynamic range digitization.

Frequently Asked Questions
How does the LTC2385IUH-18#PBF achieve both 18-bit resolution and 5 Msps throughput simultaneously?
The LTC2385IUH-18#PBF uses a successive approximation register (SAR) architecture with a 0.31 µs maximum conversion time per sample, allowing up to 5 million samples per second (5 Msps) while maintaining 18-bit resolution. The internal sample-and-hold and precision reference keep linearity error at or below 0.0015%, equivalent to roughly 0.25 LSB at 18 bits, which is exceptional for a 5 Msps SAR ADC.
What differential analog input voltage range does the LTC2385IUH-18#PBF support and how should the input driver be sized?
The LTC2385IUH-18#PBF accepts differential analog inputs from -4.076 V to +4.116 V, giving an effective full-scale span of approximately 8.2 V. The input driver amplifier must settle to 18-bit accuracy (less than 15 µV error) within half the conversion period (approximately 0.15 µs), requiring a unity-gain bandwidth of at least 50 MHz and an output slew rate above 100 V/µs for clean sampling at 5 Msps.
For precision industrial control designs, how does LTC2385IUH-18#PBF compare to a 16-bit 5 Msps ADC in terms of dynamic range improvement?
Moving from a 16-bit to the 18-bit LTC2385IUH-18#PBF adds 2 extra bits of resolution, improving theoretical dynamic range by approximately 12 dB (from about 98 dB to 110 dB SNR). In a process controller sampling a ±4 V sensor at 5 Msps, this translates to resolving signals as small as 31 µV instead of 122 µV, enabling detection of faults or process variations four times smaller than a 16-bit system would allow.
