LTC2378IMS-16#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2378IMS-16#TRPBF is a 16-bit, 1Msps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. Operating from a single 2.5V supply, it features a fully differential input range of ±VREF with VREF spanning 2.5V to 5.1V. The device achieves a typical signal-to-noise ratio (SNR) of 97dB and total harmonic distortion (THD) of –122dB at 2kHz input frequency. It consumes 13.5mW at full sampling rate and includes an internal oscillator for conversion timing. The part supports SPI-compatible serial I/O with daisy-chain capability and operates within the industrial temperature range of –40°C to 85°C.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with guaranteed no missing codes and ±0.5LSB maximum INL
• 1Msps throughput with no pipeline delay or cycle latency
• Low power consumption: 13.5mW at 1Msps, scaling down to 13.5µW in power-down mode
• Digital Gain Compression (DGC) function eliminates need for negative driver amplifier supply

Analog To Digital Converters (ADC) Applications

• Medical Imaging
• High Speed Data Acquisition
• Industrial Process Control
• Portable or Compact Instrumentation
• Automatic Test Equipment (ATE)

Analog To Digital Converters (ADC) Procurement Notes

Verify that the #TRPBF suffix indicates tape and reel packaging rather than tube packaging. Confirm the IMS designation corresponds to the industrial temperature grade (-40°C to 85°C). Ensure the order matches the specific lead-free finish and package type required for the target PCB assembly process.

Analog To Digital Converters (ADC) Selection Notes

Select this model when an industrial temperature range (-40°C to 85°C) is required instead of the commercial grade. Choose the TRPBF suffix for automated surface-mount assembly via tape and reel. Verify that the OVDD supply voltage supports the host logic levels (1.8V to 5V) and that the VREF range (2.5V to 5.1V) aligns with the system reference requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2378 family of low-power SAR ADCs, which also includes 18-bit and 20-bit variants. The IMS-16 variant specifically denotes the 16-bit resolution version packaged in a 16-lead MSOP with industrial temperature rating. It shares architectural similarities with other members like the LTC2378-18 and LTC2378-20 but offers optimized performance for applications requiring 16-bit precision at high speeds.
