LTC2376CMS-20#PBF

Analog To Digital Converters (ADC) Overview

The LTC2376CMS-20#PBF is a 20-bit, 250ksps low power SAR ADC from Analog Devices Inc. Operating from a single 2.5V supply, it features a ±VREF fully differential input range with VREF between 2.5V and 5.1V. The device achieves ±2ppm INL maximum, no missing codes at 20 bits, and 104dB SNR. It consumes 5.3mW at full throughput and includes a digital gain compression function to eliminate the need for negative driver supplies.

Analog To Digital Converters (ADC) Feature Summary

• 20-bit resolution with guaranteed no missing codes
• 250ksps sampling rate with internal oscillator
• Digital Gain Compression (DGC) for single-supply driving
• SPI-compatible serial interface supporting 1.8V to 5V logic

Analog To Digital Converters (ADC) Applications

• Medical Imaging
• High Speed Data Acquisition
• Portable or Compact Instrumentation
• Industrial Process Control
• Low Power Battery-Operated Instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #PBF indicates tube packaging for the MSOP package. Confirm the temperature grade 'C' corresponds to the 0°C to 70°C commercial range as listed in the order information table. Ensure compatibility with the 16-lead plastic MSOP footprint during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 20-bit precision and 250ksps speed are required within a low power budget of 5.3mW. The DGC feature is critical if the application requires driving the ADC from a single positive supply without a negative rail. Verify that the host system supports the SPI-compatible serial interface with daisy-chain mode capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2376 family of high-performance SAR ADCs. The CMS-20 designation specifically identifies the commercial temperature grade variant housed in a 16-lead MSOP package. Other variants include the IMS-20 for industrial temperatures and DFN packages like the CDE-20.
