LTC1409CSW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1409CSW#TRPBF is a 12-bit, 800ksps sampling analog-to-digital converter (ADC) housed in a 28-lead SO Wide package. It operates from ±5V supplies with a full-scale input range of ±2.5V and dissipates 80mW during active conversion. The device features a differential sample-and-hold with 20MHz bandwidth and 60dB common-mode rejection. Key performance metrics include 72.5dB S/(N+D) at Nyquist, ±1LSB INL/DNL, and no pipeline delay. Digital outputs interface directly with 3V logic via the OVDD pin.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the CS variant meets the required operating temperature range of 0°C to 70°C for your application environment. Ensure supply voltages remain within the specified ±5V tolerance.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high dynamic range and low power consumption. The differential input architecture is suitable for eliminating ground loops. Consider the internal reference stability if external precision references are not available in the design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1409 family of high-speed ADCs. The CSW designation specifies the commercial temperature grade and the SO Wide plastic package. It serves as a bridge between analog signals and digital processing systems where moderate resolution and high speed are balanced.

Analog To Digital Converters (ADC) Replacement Considerations

Check datasheets for alternative ADCs offering similar 12-bit resolution and 800ksps throughput. Verify pin compatibility if substituting with other SOIC-28 packages. Ensure new components support the required ±2.5V input range and shutdown functionality.
