LTC2385CUH-16#PBF

Overview

The LTC2385CUH-16#PBF is a 16-bit, 5Msps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from 5V and 2.5V supplies with a fully differential ±4.096V input range. Key electrical specifications include a typical SNR of 93.8dB at 1MHz input frequency, an SFDR of 101dB, and a maximum INL of ±0.5 LSB. The device features a serial LVDS interface, internal reference, and dissipates 78mW at full throughput.

Feature Summary

• 16-bit resolution with no missing codes and ±0.5 LSB max INL
• 5Msps sampling rate with zero pipeline latency
• Serial LVDS digital interface supporting one-lane or two-lane modes
• Internal 2.048V reference with ±20ppm/°C temperature coefficient

Applications

• High speed data acquisition systems
• Imaging applications
• Communications requiring wide dynamic range
• Control loops
• Instrumentation
• Automated test equipment (ATE)

Procurement Notes

Verify the component matches the specific package type and temperature grade. Confirm that the ordering suffix corresponds to the required tube or tape-and-reel packaging format. Ensure the voltage supply requirements align with system design constraints before procurement.

Selection Notes

Select this model for applications requiring high linearity and low noise at 5Msps. Consider the LVDS interface complexity versus standard SPI options. Evaluate power consumption against thermal management capabilities, noting the 78mW dissipation at maximum sample rate.
