LTC2367CMS-16#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2367CMS-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 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 sampling rates and achieves a typical Signal-to-Noise Ratio (SNR) of 94.7dB with no missing codes at 16 bits. It utilizes an SPI-compatible serial interface supporting logic voltages from 1.8V to 5V and includes an internal oscillator for conversion timing.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF confirms the tape and reel packaging format, distinct from the tube-packaged #PBF variant. Confirm the CMS suffix indicates the commercial temperature grade (0°C to 70°C) and MSOP package style. Ensure compatibility with external reference components such as the LTC6655-5 for optimal performance validation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 500ksps sampling rate are required within a low-power constraint. The pseudo-differential input architecture is suitable for applications needing common-mode rejection without bipolar input requirements. Ensure the host system supports the required OVDD voltage range (1.71V to 5.25V) for digital interface compatibility.
