What are the key features of LTC2385CUH-18#PBF?
- 18-bit resolution at 5 Msps enabling high-dynamic-range signal capture without accuracy-speed compromise
- 0.0015% maximum linearity error (INL) ensuring sub-LSB accuracy across the full ±4.096 V differential input range
- 0.31 µs maximum conversion time supporting 5 Msps throughput for wideband precision data acquisition
- 48-pin QFN package with differential inputs and parallel CMOS output for dense multi-channel system integration
What is LTC2385CUH-18#PBF used for?
The LTC2385CUH-18#PBF is suited for precision test and measurement instruments, medical imaging systems, and software-defined radio receivers where 18-bit dynamic range at 5 Msps simultaneously captures high-frequency signals and fine low-level detail that lower-resolution converters cannot resolve. Its low 0.0015% linearity error meets the stringent accuracy requirements of scientific instrumentation such as spectrum analysers, lock-in amplifiers, and impedance analysers. Industrial process control systems monitoring vibration, strain gauge bridges, and geophysical sensors also benefit from the device's combination of high sample rate and 18-bit precision.

Frequently Asked Questions
How does the LTC2385CUH-18's 18-bit resolution at 5 Msps compare to 16-bit alternatives for precision wideband capture?
At 18 bits, the LTC2385 resolves signals to approximately 31 µV LSB on a ±4.096 V differential range, providing 12 dB more dynamic range than a 16-bit converter with the same reference. At 5 Msps the Nyquist bandwidth reaches 2.5 MHz, enabling precise capture of wideband vibration signals, ultrasonic transducer outputs, and IF-band radio signals that exceed the bandwidth of typical 100 ksps 18-bit parts.
What is the maximum linearity error of the LTC2385CUH-18#PBF, and why does this matter for calibration systems?
The device specifies a maximum integral non-linearity (INL) of 0.0015%, equivalent to approximately ±4 LSB at 18 bits. For a calibration reference system that must maintain total measurement uncertainty below 0.005%, this 0.0015% INL contribution occupies only 30% of the error budget, leaving adequate margin for reference voltage tolerance, amplifier noise, and PCB thermal effects.
For a multi-channel data acquisition system, how does the 48-pin QFN package of LTC2385CUH-18#PBF aid channel density?
The 48-pin QFN measures approximately 7 mm × 7 mm with a 0.5 mm pitch, allowing four converter channels to fit within a 30 cm² board area when paired with a multiplexer. This density is roughly 40% smaller than the equivalent 48-pin LQFP footprint, enabling compact 8-channel or 16-channel DAQ modules for rack-mount instruments where board real estate directly limits channel count.
Which digital output interface does LTC2385CUH-18#PBF use, and how does it connect to an FPGA data capture bus?
The LTC2385 provides a parallel 18-bit CMOS output bus clocked by the converter's own BUSY signal, operating at CMOS logic levels of 0 V and 3.3 V. Connection to an FPGA requires 18 single-ended I/O pins and a simple state machine that latches data on the BUSY falling edge, achieving 5 Msps sustained throughput without a serialiser or high-speed LVDS interface, simplifying FPGA resource usage.
