LTC1278-5ISW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1278-5ISW#TRPBF is a 12-bit, 500ksps sampling analog-to-digital converter (ADC) from Analog Devices. It integrates a 200ns sample-and-hold circuit, a precision internal reference, and an internally trimmed clock. The device operates on a single +5V supply for unipolar inputs (0V to 5V) or dual ±5V supplies for bipolar inputs (±2.5V). Key electrical specifications include ±1LSB integral and differential nonlinearity, 70dB signal-to-noise plus distortion ratio at 100kHz input, and 75mW typical power dissipation. It features an 8.5mW power-down mode with instant wake-up capability.

Analog To Digital Converters (ADC) Feature Summary

• Power shutdown feature reduces consumption to 8.5mW

Analog To Digital Converters (ADC) Applications

• High-speed data acquisition systems
• Digital signal processing applications
• Multiplexed data acquisition systems
• Audio and telecom processing
• Spectrum analysis

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific speed grade suffix '-5' indicates the 500ksps throughput variant. Confirm the 'I' suffix corresponds to the industrial temperature range of -40°C to 85°C. Ensure the '#TRPBF' suffix denotes tape and reel packaging with lead-free finish. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm current availability status.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1278-5ISW#TRPBF when high-speed sampling up to 500ksps is required alongside low power consumption. The integrated 2.42V reference simplifies design by removing external components. Choose this model over the -4 speed grade if the application demands the maximum 500ksps throughput rate. Ensure the system can accommodate the 24-pin SOIC Wide package dimensions.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1278 family of 12-bit ADCs. The -5 designation specifies the faster 500ksps conversion speed compared to the -4 variant which supports 400ksps. The ISW package identifies it as an industrial temperature range device in a 24-lead plastic SOIC Wide housing. This series is designed for applications requiring a balance of speed, accuracy, and power efficiency.
