LTC2387CUH-16#PBF

Overview

The LTC2387CUH-16#PBF is a 16-bit, 15Msps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from 5V and 2.5V supplies with a power dissipation of 125mW at full throughput. The device features a serial LVDS digital interface, an internal reference buffer, and a 32-lead 5mm × 5mm QFN package. Key electrical specifications include a typical SNR of 93.8dB at 1MHz input frequency, a maximum INL of ±0.8LSB, and guaranteed 16-bit no missing codes performance.

Feature Summary

• 15Msps Throughput Rate with No Pipeline Delay or Cycle Latency
• 93.8dB Typical SNR and 102dB Typical SFDR at fIN = 1MHz
• Guaranteed 16-Bit Resolution with No Missing Codes
• ±0.8LSB Maximum Integral Nonlinearity (INL)
• Internal Reference Buffer Outputting 4.096V with 20ppm/°C Max Temperature Coefficient
• Serial LVDS Interface Supporting One-Lane and Two-Lane Output Modes

Applications

• High Speed Data Acquisition
• Imaging Systems
• Communications Applications
• Control Loops
• Instrumentation
• Automated Test Equipment (ATE)

Procurement Notes

Verify the ordering suffix #PBF indicates a lead-free finish in tube packaging. Confirm the 'C' grade designation corresponds to the commercial temperature range of 0°C to 70°C. Ensure the specific part number matches the required package type and thermal characteristics for the intended PCB layout.

Selection Notes

Select this component when low latency is critical for control loop applications due to its absence of pipeline delay. Choose the LTC2387CUH-16#PBF over the I-grade variant if the operating environment remains within the 0°C to 70°C range. Consider the internal reference buffer capabilities and LVDS interface flexibility when designing signal chains requiring high dynamic range.

Part Context

This part belongs to the LTC2387 family of SAR ADCs, which also includes the 18-bit LTC2387-18 variant. The CUH-16 designation specifically identifies the 16-bit resolution version in the commercial temperature grade housed in a 32-lead QFN package. It shares functional similarities with other high-speed ADCs but is distinct in its specific linearity and power specifications.

Replacement Considerations
