LTC2367CMS-16#PBF

Analog To Digital Converters (ADC) Overview

The LTC2367CMS-16#PBF 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 pseudo-differential unipolar input range of 0V to VREF, where VREF ranges from 2.5V to 5.1V. The device consumes 6.8mW at maximum throughput and achieves a typical signal-to-noise ratio (SNR) of 94.7dB with no missing codes over the full 16-bit range. It includes an internal oscillator, SPI-compatible serial interface supporting 1.8V to 5V logic, and daisy-chain mode capabilities.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with guaranteed no missing codes and ±0.75LSB maximum integral nonlinearity (INL)
• 500ksps sampling rate with zero cycle latency and internal conversion clock
• Low power consumption of 6.8mW at 500ksps, scaling down to 6.8µW in power-down mode
• SPI-compatible serial I/O with daisy-chain support for 1.8V, 2.5V, 3.3V, and 5V logic levels

Analog To Digital Converters (ADC) Applications

• Medical imaging systems
• 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 package variant, as the CMS suffix denotes a 16-lead plastic MSOP package. Confirm the temperature grade corresponds to the C-grade specification (0°C to 70°C). Ensure the ordering suffix #PBF indicates lead-free finish compliance. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm availability and exact pinout configuration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit SAR ADC with high speed and low power is required. The pseudo-differential input architecture reduces common-mode noise. Ensure the external reference voltage falls within the 2.5V to 5.1V range. Verify that the host system logic voltage matches the OVDD supply range of 1.71V to 5.25V. Consider the thermal dissipation characteristics if operating near the upper limits of the specified temperature range.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2367-16 family of low noise, low power SAR ADCs. Other variants in the series include the IMS (–40°C to 85°C) and HMS (–40°C to 125°C) temperature grades, as well as DFN package options like the IDE-16. The CMS-16 specifically refers to the commercial temperature grade version in the MSOP package.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include LTC2367IMS-16#PBF for extended industrial temperature range and LTC2367HMS-16#PBF for automotive/extended range. Package alternatives include LTC2367CDE-16#PBF (DFN). Verify pin compatibility and electrical specifications before substitution.
