LTC1419CG#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1419CG#TRPBF is a 14-bit, 800ksps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices. It operates from ±5V supplies with a typical power dissipation of 150mW. The device features a true differential input sample-and-hold circuit with a ±2.5V input range and a 20MHz full-power bandwidth. Key performance metrics include an 81.5dB signal-to-(noise + distortion) ratio at 100kHz input and 93dB total harmonic distortion. It integrates a precision 2.5V internal reference and offers two digitally selectable shutdown modes: Nap and Sleep.

Analog To Digital Converters (ADC) Applications

• Telecommunications systems
• Digital signal processing interfaces
• Multiplexed data acquisition systems
• High speed data acquisition applications
• Spectrum analysis equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging and lead-free compliance. Confirm the 'C' grade designation corresponds to the commercial operating temperature range of 0°C to 70°C. Ensure the specific package variant matches the required board layout, as the CG suffix denotes the SSOP-28 package.

Analog To Digital Converters (ADC) Selection Notes

Select this component when bipolar input signals within the ±2.5V range are required. The differential architecture is suitable for eliminating ground loops and rejecting common mode noise. Verify that the system can accommodate ±5V supply rails, as the device is optimized for this voltage configuration. Consider the 150mW power consumption if thermal management is a constraint in the design.

Analog To Digital Converters (ADC) Part Context

The LTC1419 belongs to the LTC1419 family of high-speed ADCs. The CG#TRPBF designation specifies the Commercial temperature grade, SSOP-28 plastic package, and Tape & Reel packaging format. Other variants in the series include the I-grade for industrial temperatures and SW packages for SOIC footprints.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the LTC1419CSW#TRPBF (SOIC-28 package) or the LTC1419IG#PBF (Industrial grade, SSOP-28). Verify that any substitute maintains the 14-bit resolution and 800ksps throughput requirements.
