LTC2364IDE-16#PBF

Analog To Digital Converters (ADC) Overview

The LTC2364IDE-16#PBF is a 16-bit, 250ksps 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 SNR of 94.7dB at fIN = 2kHz with ±0.75LSB maximum INL and guaranteed 16-bit no missing codes. Power consumption is 3.4mW at 250ksps. It includes an internal oscillator, auto power-down, and an SPI-compatible serial interface supporting 1.8V to 5V logic levels.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #PBF indicates lead-free finish and tube packaging. Confirm the 'I' grade designation corresponds to the –40°C to 85°C operating temperature range. Ensure the package type matches the 16-Lead (4mm × 3mm) Plastic DFN specification. Cross-reference the manufacturer part number LTC2364IDE-16#PBF with official Analog Devices documentation to confirm current production status and availability.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit SAR ADC with low power consumption and high speed is required. The pseudo-differential input architecture reduces common-mode noise. Ensure the application supports a 2.5V analog supply and a separate digital I/O supply (OVDD) between 1.71V and 5.25V. Verify that the external reference voltage falls within the 2.5V to 5.1V range. Consider the thermal performance of the DFN package if operating near the upper temperature limits.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2364 family of low noise, low power, high speed SAR ADCs. The IDE-16 variant specifically denotes the industrial temperature grade (-40°C to 85°C) and the DFN package. Other variants include the CMS-16 (commercial grade, MSOP), IMS-16 (industrial grade, MSOP), and H-grade parts for extended temperature operation up to 125°C.

Analog To Digital Converters (ADC) Replacement Considerations

Compatible substitutes within the same family include LTC2364IMS-16#PBF (MSOP package, same temp grade) and LTC2364HMS-16#PBF (extended temp). For pin-compatible alternatives with different packages, consider LTC2364CDE-16#PBF (commercial grade DFN). Verify electrical parameters and package dimensions before substitution.
