LTC2367IMS-16#PBF

Analog To Digital Converters (ADC) Overview

The LTC2367IMS-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 achieves ±0.75LSB maximum integral nonlinearity (INL), guaranteed no missing codes at 16 bits, and a typical signal-to-noise ratio (SNR) of 94.7dB. Power consumption is 6.8mW at full throughput, scaling down significantly in power-down mode. It includes an internal oscillator and supports SPI-compatible serial interfaces with daisy-chain capability.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #PBF indicates lead-free finish and tube packaging for the IMS grade. Confirm the temperature range is –40°C to 85°C. Check datasheet specifications for absolute maximum ratings regarding supply voltages and input clamping diodes to ensure safe operating conditions during integration.

Analog To Digital Converters (ADC) Selection Notes

Select the IMS grade for industrial temperature ranges (–40°C to 85°C). Ensure the external reference voltage is within the 2.5V to 5.1V range to maintain specified accuracy. Use the OVDD pin to match the host digital logic voltage level between 1.71V and 5.25V. Consider the LT6202 buffer amplifier for driving bipolar signals into the unipolar input range.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2367-16 family of low noise, high-speed SAR ADCs. Other variants include the CMS grade (0°C to 70°C) and HMS grade (–40°C to 125°C), as well as DFN package options like the IDE-16. All share identical electrical characteristics but differ in temperature rating and physical package.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same family include LTC2367CMS-16#PBF for commercial temperature ranges and LTC2367HMS-16#PBF for extended industrial temperatures. Package alternatives such as LTC2367IDE-16#PBF offer the same electrical performance in a 4mm × 3mm DFN footprint.
