LTC1419CSW#PBF

Analog To Digital Converters (ADC) Overview

The LTC1419CSW#PBF is a 14-bit, 800ksps successive approximation register (SAR) analog-to-digital converter in a 28-lead plastic SO package. It operates from ±5V supplies with a total power dissipation of 150mW. The device features a true differential input sample-and-hold with a ±2.5V range and a 20MHz full-power bandwidth. Key performance metrics include an 81.5dB signal-to-(noise + distortion) ratio at 100kHz input and 93dB THD. It integrates a 2.5V internal reference and offers two digitally selectable shutdown modes: nap and sleep.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component matches the specific Analog Devices part number LTC1419CSW#PBF. Confirm the suffix #PBF indicates lead-free compliance and SW denotes the 28-lead SO package. Ensure the operating temperature range aligns with the C grade specifications (0°C to 70°C). Check for authenticity through authorized distribution channels.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 14-bit SAR ADC with parallel output and no pipeline delay is required. It is suitable for applications needing a 20MHz input bandwidth and bipolar ±2.5V input range. Consider the 150mW power consumption and the need for ±5V supplies. The integrated reference simplifies design compared to external reference solutions.

Analog To Digital Converters (ADC) Part Context

The LTC1419 belongs to the Linear Technology (now Analog Devices) family of high-speed sampling A/D converters. The CSW variant specifically refers to the commercial temperature grade version housed in a 28-lead plastic Small Outline package. This model is designed for systems requiring direct microprocessor interfacing via its 14-bit parallel data port.
