LTC2364HMS-16#PBF

Analog To Digital Converters (ADC) Overview

The LTC2364HMS-16#PBF is a 16-bit, 250ksps 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, with VREF supported between 2.5V and 5.1V. The device achieves ±0.75LSB maximum integral nonlinearity, guaranteed 16-bit no missing codes, and a typical signal-to-noise ratio of 94.7dB at an input frequency of 2kHz. Power consumption is 3.4mW at full throughput, scaling down to 3.4µW at 250sps. It includes an internal oscillator, SPI-compatible serial interface supporting 1.8V to 5V logic, and daisy-chain mode.

Analog To Digital Converters (ADC) Applications

• Medical imaging systems
• High-speed data acquisition
• Portable or compact instrumentation
• Industrial process control
• Low-power battery-operated instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the H-grade suffix indicates the –40°C to 125°C operating temperature range. Confirm the MSOP-16 package type matches the design requirements. Ensure the external reference voltage is within the 2.5V to 5.1V range for proper operation. Check that the digital interface voltage (OVDD) is compatible with the host system's logic levels between 1.8V and 5V.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high accuracy and low power are required in a small footprint. The H-grade version is necessary for applications operating up to 125°C. The pseudo-differential input simplifies front-end design compared to true differential ADCs. Ensure the application can provide a stable external reference voltage, as the device does not include an internal reference.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2364-16 family of 16-bit SAR ADCs. The 'H' suffix denotes the extended industrial temperature range (-40°C to 125°C), while 'M' indicates the MSOP-16 package. Other variants include C-grade (0°C to 70°C) and I-grade (-40°C to 85°C) options, available in both MSOP and DFN packages.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2364IMS-16#PBF (I-grade, -40°C to 85°C) and LTC2364CDE-16#PBF (C-grade, 0°C to 70°C). Verify temperature specifications match the application environment before substituting.
