LTC1401IS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1401IS8#PBF is a complete 12-bit, 200ksps analog-to-digital converter (ADC) housed in an 8-lead plastic SO package. It operates from a single 3V supply and draws 15mW during normal conversion. The device integrates a precision internal 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 of 0V to 2.048V with a full-scale drift of 45ppm/°C.

Analog To Digital Converters (ADC) Feature Summary

• 3-wire serial interface compatible with DSPs and microprocessors

Analog To Digital Converters (ADC) Applications

• Low power and battery-operated systems
• Handheld or portable instruments
• High-speed data acquisition
• Multiplexed data acquisition systems
• Telecommunication and digital radio applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #PBF indicates lead-free compliance. Confirm the IS8 variant corresponds to the industrial temperature range (-40°C to 85°C). Ensure the package type matches the 8-lead plastic SO specification for board layout compatibility.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low power consumption and high accuracy in a compact footprint. The internal reference eliminates external components for standard 0V to 2.048V inputs. Consider the 315ns acquisition time when selecting driving amplifiers to ensure proper settling before conversion.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1401 family of complete, low-power ADCs. The 'I' suffix denotes the industrial temperature grade, while 'S8' specifies the 8-lead SO package. The '#PBF' suffix confirms lead-free manufacturing. It serves as a cost-effective solution for mid-resolution data acquisition tasks.
