LTC2387CUH-16#TRPBF

Overview

The LTC2387CUH-16#TRPBF 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 differential input range of ±4.096V. Key electrical specifications include a typical SNR of 93.8dB at 1MHz input frequency, a maximum INL of ±0.8LSB, and power dissipation of 125mW at full throughput. The device features an internal reference buffer outputting 4.096V and utilizes a serial LVDS digital interface for data transmission. It is housed in a 32-lead 5mm × 5mm QFN package and supports an operating temperature range of 0°C to 70°C.

Feature Summary

• 16-bit resolution with guaranteed no missing codes and ±0.8LSB maximum integral nonlinearity.
• 15Msps sampling rate with zero pipeline delay and cycle latency.
• Serial LVDS interface supporting one-lane and two-lane output modes.
• Internal precision reference buffer providing 4.096V output with ±20ppm/°C temperature coefficient.

Applications

• High-speed data acquisition systems
• Imaging applications requiring wide dynamic range
• Communications equipment with significant signal bandwidth
• High-speed control loop applications
• Instrumentation and automated test equipment

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the 'C' grade designation aligns with the required commercial temperature range of 0°C to 70°C for the intended deployment environment. Cross-reference the manufacturer part number with authorized distribution channels to ensure authenticity and traceability.

Selection Notes

Select the LTC2387CUH-16#TRPBF when a low-latency SAR ADC is required for control loops or imaging. Ensure the system design accommodates the 5V analog supply and 2.5V digital/logic supplies. Verify that the driving circuitry can settle within the acquisition time defined by the 15Msps clock rate. Consider the LVDS interface requirements for PCB layout and termination if utilizing the high-speed serial output mode.

Part Context

This component belongs to the LTC2387 family of high-speed SAR ADCs, which also includes the 18-bit LTC2387-18 variant. The CUH-16#TRPBF specifically denotes the 16-bit resolution version in the commercial temperature grade, packaged in a QFN format. It is designed to complement development tools such as the DC2290A-B demonstration board for performance evaluation.

Replacement Considerations

The LTC2387IUH-16#TRPBF serves as the industrial temperature grade equivalent (-40°C to 85°C). The LTC2387-18 offers higher 18-bit resolution but shares the same package and interface characteristics. Direct pin-compatible substitutes outside this family require verification of voltage levels, interface protocols, and timing parameters.
