LTC1274CSW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1274CSW#TRPBF is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 5V or ±5V supply, consuming 10mW at a sampling rate of 100ksps. The device features a single-ended input, an internal 2.42V reference, and a parallel data interface in a 24-lead SOIC package. It supports unipolar (0V to 4.096V) and bipolar (±2.048V) input ranges with a shutdown current of 1µA.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with 100ksps sampling rate
• Low power consumption: 10mW active, 1µA shutdown
• Internal synchronized clock and precision reference
• Single-ended input with parallel digital output

Analog To Digital Converters (ADC) Applications

• Battery-powered portable systems
• High-speed data acquisition for PCs
• Multiplexed data acquisition systems
• Audio and telecom processing

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape-and-reel packaging when sourcing. Confirm the CSW variant meets commercial temperature requirements (0°C to 70°C). Ensure the specific distributor listing matches the Analog Devices manufacturer identification.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low power SAR ADCs with single-ended inputs. The LTC1277 is the differential input alternative within the same family. Verify that the 12-bit resolution and 100ksps speed align with system bandwidth requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1274/LTC1277 series of 12-bit, 10mW ADCs. The 'C' designation specifies the commercial operating temperature range. The '#PBF' indicates lead-free and RoHS compliance. The 'SW' denotes the 24-lead plastic SO wide package.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1277 offers differential inputs and a two-byte read format but shares similar power and speed characteristics. Other 12-bit SAR ADCs may require external references or different interface protocols.
