LTC2338HMS-18#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2338HMS-18#TRPBF is an 18-bit, 1Msps successive approximation register (SAR) analog-to-digital converter with fully differential inputs. Operating from a single 5V supply, it features a ±10.24V true bipolar input range and achieves 100dB SNR. The device includes an onboard 2.048V temperature-compensated reference with a low drift of 20ppm/°C max and a single-shot capable reference buffer. It supports SPI-compatible serial I/O with daisy-chain mode and operates across an extended temperature range of –40°C to 125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the H-grade designation ensures operation up to 125°C. Check RoHS compliance status in the specific datasheet revision. Ensure the ordering information matches the required package type and temperature range.

Analog To Digital Converters (ADC) Selection Notes

Select this part for high-voltage applications requiring wide dynamic range without external level shifting. The internal reference simplifies design but allows overdriving for higher accuracy. Ensure the host interface logic voltage matches the OVDD supply range of 1.71V to 5.25V. Consider the 16-lead MSOP package constraints for thermal management.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2338 family of low-power, high-speed ADCs. The 'H' suffix denotes the industrial/high-temperature grade variant, while 'M' indicates the MSOP package. The '#TRPBF' suffix specifies tape and reel packaging with lead-free finish. It complements lower resolution variants like the LTC2338-16 for precision measurement tasks.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2338IMS-18#TRPBF for commercial temperature range (0°C to 70°C). For lower speed requirements, consider LTC2338-16 variants. Verify that any substitute maintains the 18-bit resolution and 1Msps throughput if performance parity is required.
