LTC2382CDE-16#TRPBF

Overview

The LTC2382CDE-16#TRPBF is a 16-bit, 500ksps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 2.5V supply and features a ±2.5V fully differential input range. The device consumes 6.5mW at maximum sampling rate and achieves 92dB SNR with guaranteed 16-bit no missing codes performance. It utilizes an SPI-compatible serial interface supporting 1.8V to 5V logic levels and includes daisy-chain capability. The component is housed in a 16-lead DFN package.

Feature Summary

• 16-bit resolution with 500ksps throughput and 92dB typical SNR
• Low power consumption of 6.5mW at full speed, scaling down to 13µW at 1ksps
• SPI-compatible serial interface with daisy-chain mode for multi-channel systems
• Extended acquisition time of 1.25µs enabling the use of low-power ADC drivers

Applications

• Medical imaging systems
• High-speed data acquisition
• Portable or compact instrumentation
• Industrial process control
• Automated test equipment (ATE)

Procurement Notes

Verify that the specific part number suffix #TRPBF corresponds to the tape and reel packaging format as indicated in the manufacturer's ordering information. Confirm the temperature grade matches the application requirements, as the C-grade variant supports 0°C to 70°C operation. Ensure the external reference voltage is within the specified 2.4V to 2.6V range to maintain accuracy specifications.

Selection Notes

Select this component when a high-speed, low-power SAR ADC with differential inputs is required. The extended 1.25µs acquisition time allows for simpler driver circuits compared to faster SAR ADCs. Ensure the system can provide a stable 2.5V analog supply and an external reference voltage between 2.4V and 2.6V. Verify that the host microcontroller supports the required SPI clock speeds and timing constraints for reliable data transfer.

Part Context

This part belongs to the LTC2382-16 family of low-power SAR ADCs. It shares architectural similarities with the LTC2380-16 but offers lower power consumption and slightly different performance characteristics suited for cost-sensitive applications. The DFN package provides a compact footprint suitable for space-constrained designs.

Replacement Considerations

The LTC2382CDE-16#PBF is the tube-packaged equivalent of this tape-and-reel part. For higher temperature operation, the LTC2382HDE-16#TRPBF supports up to 125°C. Cross-model replacements like the LTC2380-16 offer similar functionality but with different power and noise profiles.
