LTC2367IDE-18#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2367IDE-18#TRPBF is an 18-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 achieves a typical Signal-to-Noise Ratio (SNR) of 97dB, ±2.5LSB maximum Integral Nonlinearity (INL), and guaranteed 18-bit no missing codes. Power consumption is 6.8mW at full throughput, scaling down to microamps in power-down mode. It utilizes an internal oscillator and supports SPI-compatible serial I/O with daisy-chain capability.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging for the IDE package variant. Confirm the temperature grade corresponds to the 'I' designation, covering –40°C to 85°C. Ensure the source documentation matches the specific part number to avoid confusion with MSOP packages or different temperature grades such as C or H.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 18-bit accuracy and 500ksps throughput are required within a low power budget. The pseudo-differential input architecture suits applications needing common-mode noise rejection without differential signal sources. Ensure the host system provides a stable 2.5V analog supply and compatible digital I/O voltage via OVDD. Consider external buffering if driving high-impedance sources to maintain distortion specifications.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2367 family of SAR ADCs, which offers various resolutions and input configurations. The IDE package denotes a 16-lead, 4mm × 3mm plastic DFN form factor. The 'I' suffix specifies the industrial temperature range. Other variants include CMS (MSOP, commercial temp) and HMS (MSOP, extended temp).
