LTC1409CG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1409CG#PBF is a 12-bit, 800ksps successive approximation analog-to-digital converter (ADC) from Analog Devices. It operates on ±5V supplies with a power dissipation of 80mW. The device features a true differential input sample-and-hold with a ±2.5V full-scale range and a 20MHz bandwidth. Key performance metrics include 72.5dB S/(N+D) at the Nyquist frequency, ±1LSB INL/DNL, and no pipeline delay. It integrates a precision internal reference and offers two digitally selectable shutdown modes: Nap (4mW) and Sleep (10μW).

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type matches the 'G' suffix for the 28-lead plastic SO package. Confirm the temperature grade corresponds to the 'C' suffix for commercial operation (0°C to +70°C). Ensure the '#PBF' suffix indicates lead-free RoHS compliance. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm availability and current manufacturing status.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high dynamic range and low power consumption. The 80mW power dissipation is suitable for battery-operated systems when utilizing the Nap or Sleep modes. The differential input architecture eliminates ground loops and common-mode noise. Ensure the driving source impedance is low or buffered to meet the 150ns acquisition time requirement for full throughput.

Analog To Digital Converters (ADC) Part Context

The LTC1409 is part of the LTC1409 series of sampling ADCs. The 'CG' designation specifies the 28-lead SO Wide package and Commercial temperature range. The '#PBF' suffix denotes a Pb-free finish compliant with RoHS standards. This specific variant is designed for general-purpose data acquisition where moderate speed and high accuracy are required.
