LTC1404IS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1404IS8#TRPBF is a complete 12-bit, 600ksps Analog-to-Digital Converter (ADC) housed in an 8-lead plastic SO package. It operates from a single +5V supply or ±5V supplies, consuming 75mW at full speed. The device integrates a 160ns sample-and-hold circuit and a precision 2.43V internal reference. Key electrical specifications include ±1LSB Integral Nonlinearity (INL), ±1LSB Differential Nonlinearity (DNL), and no missing codes over the operating temperature range (-40°C to 85°C). AC performance guarantees 72dB Signal-to-(Noise+Distortion) ratio and -80dB Total Harmonic Distortion at Nyquist frequency.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Applications

• High-speed data acquisition systems
• Digital signal processing front-ends
• Audio and telecom processing equipment
• Battery-operated portable instruments

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix #TRPBF confirms the component is supplied in Tape and Reel format and is Lead Free compliant. Confirm the 'I' suffix indicates the Industrial temperature grade (-40°C to 85°C). Ensure the source documentation matches the specific lot and revision for regulatory compliance checks such as RoHS status.

Analog To Digital Converters (ADC) Selection Notes

Select this part for applications requiring high throughput (600ksps) with low power constraints. Use the Nap mode for instant wake-up scenarios requiring 7.5mW consumption. Choose bipolar operation if input signals span negative voltages by connecting VSS to -5V. Ensure the driving amplifier can settle within the 160ns acquisition time to maintain accuracy.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1404 family of monolithic sampling ADCs. The 'IS8' designation specifies the Industrial temperature range and the 8-lead SOIC package. The '#TRPBF' suffix denotes the specific packaging configuration (Tape and Reel) and material composition (Lead-Free/Biocompliant).

Analog To Digital Converters (ADC) Replacement Considerations

Public datasheets identify the DAC-8043 as a pin-compatible replacement target for the LTC8043 DAC series, but do not list direct cross-model substitutes for the LTC1404 ADC. Verify functional compatibility with existing designs if substituting with other 12-bit SAR ADCs.
