LTC2368HMS-16#PBF

Analog To Digital Converters (ADC) Overview

The LTC2368HMS-16#PBF is a 16-bit, 1Msps 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 13.5mW at 1Msps and achieves ±0.75LSB maximum integral nonlinearity with no missing codes. It delivers a typical signal-to-noise ratio of 94.7dB and total harmonic distortion of –118dB. The H-grade variant supports an operating temperature range of –40°C to 125°C and is housed in a 16-lead MSOP package.

• 16-bit resolution with guaranteed no missing codes and ±0.75LSB max INL
• 1Msps throughput rate with internal oscillator and auto power-down
• SPI-compatible serial interface supporting 1.8V to 5V I/O logic levels
• Low power consumption: 13.5mW at 1Msps, scaling down to 2.25µW in shutdown

Analog To Digital Converters (ADC) Applications

• Medical imaging systems
• High-speed data acquisition
• Portable or compact instrumentation
• Industrial process control
• Automatic test equipment (ATE)

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix for the required temperature grade. The 'H' suffix denotes the extended industrial range of –40°C to 125°C. Confirm the package type matches the design requirements, as this part number specifies the 16-lead MSOP format. Ensure the external reference voltage falls within the 2.5V to 5.1V specification to maintain performance guarantees.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2368HMS-16#PBF when operation up to 125°C is required. For commercial applications (0°C to 70°C), consider the CMS variant; for automotive/extended industrial (-40°C to 85°C), use the IMS variant. The pseudo-differential input architecture simplifies driving circuits compared to true differential ADCs. Ensure the host system provides a stable 2.5V supply for VDD and a compatible voltage between 1.71V and 5.25V for OVDD.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2368 family of low-power, high-speed SAR ADCs. The H-grade designation specifically extends the operational temperature limit to 125°C compared to standard commercial grades. It shares architectural similarities with the LTC2367 series but offers higher sampling rates and resolution options within the same power envelope.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Direct replacements require matching the 16-bit resolution, 1Msps speed, MSOP package, and –40°C to 125°C temperature range.
