LTC1401CS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1401CS8#PBF is a complete, single-supply 12-bit analog-to-digital converter (ADC) housed in an 8-lead plastic SO package. It operates from a 3V supply and achieves a sampling rate of 200ksps with typical power dissipation of 15mW. The device integrates a precision 1.2V reference and a 315ns sample-and-hold circuit. Key electrical specifications include ±1LSB integral nonlinearity (INL), ±1LSB differential nonlinearity (DNL), and no missing codes over the operating temperature range. It supports unipolar input ranges from 0V to 2.048V and features a 3-wire serial interface compatible with DSPs and microprocessors.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component marking '1401' on the S8 package to confirm authenticity. Ensure the ordering suffix #PBF indicates lead-free compliance. Confirm that the CS8 variant meets the required commercial temperature range of 0°C to 70°C for the specific application environment.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1401CS8#PBF when a single 3V supply and low power consumption are critical constraints. This model is suitable for applications requiring up to 200ksps throughput with 12-bit resolution. Consider the IS8 variant if operation below 0°C is required. Ensure the analog input signal remains within the 0V to 2.048V range defined by the internal reference.

Analog To Digital Converters (ADC) Part Context

The LTC1401 belongs to the Linear Technology (now Analog Devices) family of complete, easy-to-use ADCs. It is part of a series that includes variants like the LTC1400 and LTC1404, which offer different sampling rates but share similar packaging and feature sets. The CS8 designation specifically identifies the commercial temperature grade version in the SO-8 package.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should verify pin compatibility and electrical specifications against other members of the LTC140x family or comparable 12-bit SAR ADCs from Analog Devices.
