Applications
The LTC2387IUH-18#TRPBF is designed for high-speed precision data acquisition in test and measurement instruments, medical imaging equipment, and software-defined radio (SDR) receivers that require 18-bit resolution at multi-megasample rates. Its low 0.0011% linearity error and 63ns maximum conversion time make it ideal for spectrum analyzers, high-resolution oscilloscopes, and radar signal processing front-ends. The differential input architecture with wide ±4.1V swing supports direct connection to low-noise analog front-end circuits without additional attenuation.

Frequently Asked Questions
What resolution and conversion speed does LTC2387IUH-18#TRPBF offer for high-speed data acquisition?
The LTC2387IUH-18#TRPBF provides 18-bit resolution with a maximum conversion time of 0.063µs (63ns), corresponding to sample rates up to approximately 15.6Msps. This combination of 18-bit resolution and high throughput makes it one of the faster precision SAR ADCs available, suited for wideband signal digitization in test instruments and radar receivers requiring both speed and dynamic range.
What is the analog input voltage range of the LTC2387IUH-18#TRPBF, and how does this benefit bipolar signal sources?
The LTC2387IUH-18#TRPBF accepts differential analog inputs from -4.09V to +4.102V, providing a bipolar input range of approximately ±4.1V. This wide differential range allows direct connection to bipolar signal sources such as AC-coupled sensors, differential amplifier outputs, and instrumentation amplifier stages without needing additional level-shift circuits, simplifying front-end design in precision measurement systems.
How does the 18-bit linearity specification of LTC2387IUH-18#TRPBF compare to lower-resolution ADCs for precision measurement?
With a maximum linearity error of 0.0011% (approximately 1.1ppm or 0.07 LSB at 18-bit), the LTC2387IUH-18#TRPBF is extremely linear for its resolution class. A 16-bit ADC at the same linearity spec would show about 0.28 LSB error — four times more visible in the digital code. This superior linearity is critical in precision weighing scales, medical diagnostic equipment, and high-accuracy waveform generators where deviation from ideal transfer function must be minimized.
