LTC1409ISW#PBF

Analog To Digital Converters (ADC) Overview

The LTC1409ISW#PBF is a 12-bit, 800ksps sampling analog-to-digital converter (ADC) manufactured by Analog Devices (formerly Linear Technology). It utilizes a successive approximation register (SAR) architecture and features an internal reference. The device supports differential, pseudo-differential, or single-ended input configurations via a parallel interface. Key electrical specifications include a maximum power dissipation of 35 mW, a shutdown mode for low-power applications, and an operating temperature range from -40°C to +85°C. It is housed in a 20-lead SOIC package.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with 800ksps sampling rate
• Internal voltage reference reduces external component count
• Flexible input modes: differential, pseudo-differential, or single-ended
• Shutdown mode minimizes power consumption

Analog To Digital Converters (ADC) Applications

• Portable instrumentation systems requiring low power
• Industrial process control data acquisition
• Battery-powered measurement devices
• Medical equipment signal conditioning

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer designation as Analog Devices Inc., which acquired Linear Technology. Confirm the suffix #PBF indicates lead-free compliance. Check current availability status as distribution may vary by region. Ensure the SOIC-20 package matches the design footprint requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between moderate speed (800ksps) and high resolution (12-bit) is required. Compare against the LTC1419 if 14-bit resolution is necessary, noting the increased pin count and power. Consider the LTC1403 if serial interface and higher speed are preferred over parallel connectivity.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC14xx series of high-speed, low-power ADCs. It serves as a mid-range option within the portfolio, offering more resolution than the 10-bit LTC1407 but less than the 14-bit LTC1419. It is designed for applications where power efficiency is critical alongside adequate precision.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes include the LTC1409ACSW#PBF (commercial grade) and the LTC1409IMS#PBF (MSOP package). For upgraded performance, the LTC1419 offers 14-bit resolution. Lower resolution alternatives include the LTC1407.
