LTC1401IS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1401IS8#TRPBF 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 active conversion. 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 features a 3-wire serial interface compatible with DSPs and microprocessors.

Analog To Digital Converters (ADC) Feature Summary

• Complete 12-Bit ADC with internal reference in SO-8 package
• Single 3V supply operation with 15mW typical power dissipation
• Three power-saving modes: Nap (1.5mW), Sleep (19.5µW), and Shutdown (13.5µW)
• High impedance analog input with 0V to 2.048V unipolar range

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix #TRPBF confirms the component is supplied in tape and reel packaging and is lead-free compliant. Confirm the IS8 suffix corresponds to the industrial temperature range of –40°C to 85°C. Ensure the source documentation matches the Analog Devices datasheet for the LTC1401 family to validate pinout and electrical characteristics.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring a low-pin-count, single-supply ADC with integrated reference. The 200ksps sampling rate and 12-bit resolution are suitable for general-purpose data acquisition. Consider the specific power-down modes if energy efficiency is critical; the device supports immediate wake-up from Nap mode. 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 is part of the Linear Technology (now Analog Devices) portfolio of high-speed, low-power data converters. It utilizes a successive approximation register (SAR) architecture with an internal capacitive DAC. The device is designed to interface directly with microprocessors via a standard 3-wire serial port, simplifying system design compared to parallel ADCs.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitutes include the LTC1400 (400ksps) and LTC1404 (600ksps). These devices share similar pinouts and functionality but offer higher sampling rates. Verify compatibility regarding clock frequencies and power consumption when substituting.
