LTC2369IDE-18#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2369IDE-18#TRPBF is an 18-bit, 1.6Msps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. Operating from a single 2.5V supply, it 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 96.5dB and maximum Integral Nonlinearity (INL) of ±2.5LSB with no missing codes at 18 bits. Power consumption is 18mW at full throughput, scaling down to 18μW in power-down mode. It includes 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 confirms the tape and reel packaging format and the IDE designation indicates the industrial temperature grade (-40°C to 85°C). Confirm that the specific lot requires compliance with RoHS directives as indicated by the lead-free finish. Ensure the procurement source provides valid traceability for the Analog Devices manufacturer part number.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 18-bit resolution and 1.6Msps throughput are required within a low-power constraint. The pseudo-differential input architecture is suitable for applications requiring common-mode noise rejection. Ensure the host system supports the required 2.5V analog supply and compatible digital I/O voltage levels between 1.8V and 5V. Consider the DFN package thermal characteristics if operating near the upper temperature limit.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2369 family of high-performance SAR ADCs. The 'I' suffix denotes the industrial temperature range (-40°C to 85°C), while 'H' would indicate extended range up to 125°C. The 'DE' package code specifies the 16-lead 4mm x 3mm plastic DFN form factor. The '#TRPBF' suffix designates the tape and reel quantity and lead-free finish status.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs if considering alternative SAR ADCs from other manufacturers, specifically regarding pinout, supply voltage requirements, and interface timing.
