LTC2370IMS-16#PBF

Analog To Digital Converters (ADC) Overview

The LTC2370IMS-16#PBF is a 16-bit, 2Msps 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 dissipates 19mW at full throughput and achieves ±0.85LSB maximum integral nonlinearity with no missing codes at 16 bits. It delivers a typical signal-to-noise ratio of 94dB and total harmonic distortion of –112dB. The component supports SPI-compatible serial I/O with logic levels from 1.8V to 5V via the OVDD pin and includes an internal oscillator for conversion timing.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #PBF indicates lead-free finish and tube packaging. Confirm the IMS suffix corresponds to the industrial temperature range of –40°C to 85°C. Ensure the package type matches the 16-lead plastic MSOP specification. Cross-reference the manufacturer part number with official Analog Devices documentation to validate authenticity and specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit SAR ADC with 2Msps throughput and low power dissipation is required. The pseudo-differential unipolar input range suits applications referencing ground. Ensure the external reference voltage falls within the 2.5V to 5.1V range. Verify that the host system logic voltage aligns with the OVDD supply range of 1.71V to 5.25V for proper digital interface operation.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2370-16 family of 16-bit SAR ADCs. The IMS suffix specifically denotes the industrial temperature grade (–40°C to 85°C) housed in a 16-lead MSOP package. Other variants include the C-grade (0°C to 70°C) and H-grade (–40°C to 125°C), available in both MSOP and DFN packages.
