LTC2387IUH-16#PBF

Overview

The LTC2387IUH-16#PBF is a low-noise, high-speed 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates at a throughput rate of 15Msps with no pipeline delay or cycle latency. The device features a serial LVDS digital interface and accepts differential inputs with an 8.192Vp-p range. Key electrical specifications include a typical SNR of 93.8dB at 1MHz input frequency, a maximum INL of ±0.8LSB, and guaranteed 16-bit resolution without missing codes. Power consumption is 125mW at full speed, utilizing 5V and 2.5V supplies within the industrial temperature range of –40°C to 85°C.

Feature Summary

• 16-Bit Resolution with No Missing Codes
• 15Msps Throughput Rate with Zero Latency
• Serial LVDS Digital Interface
• Internal 2.048V Reference with ±20ppm/°C Max Coefficient

Applications

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

Procurement Notes

Verify that the component suffix #PBF indicates a lead-free finish and tube packaging. Confirm the 'I' grade designation corresponds to the industrial operating temperature range of –40°C to 85°C. Ensure the QFN-32 package matches the required PCB footprint dimensions of 5mm × 5mm.

Selection Notes

Select this model for applications requiring high linearity and wide dynamic range at 15Msps. The internal reference buffer outputs 4.096V; if external references are used, tie REFIN to GND to disable the internal buffer. Ensure the driving circuit can settle within the acquisition time to maintain specified INL and THD performance.

Part Context

This part belongs to the LTC2387 family of SAR ADCs. The 'I' suffix denotes the industrial temperature grade, while 'UH' specifies the 32-lead plastic QFN package. The '#PBF' suffix confirms lead-free manufacturing compliance. It shares functional architecture with the LTC2387-18 but offers lower resolution for optimized power and cost in specific bandwidth applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin compatibility and electrical parameters against alternative SAR ADCs from other manufacturers if sourcing constraints require it.
