LTC1416CG

Analog To Digital Converters (ADC) Overview

The LTC1416CG is a low-power, 14-bit successive approximation analog-to-digital converter (ADC) operating at sampling rates up to 400ksps. It draws 70mW from dual ±5V supplies and features a high dynamic range differential sample-and-hold circuit with a 15MHz full power bandwidth. The device includes an internal precision 2.5V reference and offers two digitally selectable shutdown modes: Nap and Sleep. It provides a 14-bit parallel output interface compatible with microprocessors and DSPs, ensuring no pipeline delay in conversion results.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific package variant against the datasheet. The 'C' suffix indicates the commercial temperature range (0°C to 70°C). Confirm that the required supply voltages match the specified ±5V operation and ensure the application supports the parallel digital interface requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 14-bit resolution and 400ksps throughput are required with minimal external support circuitry. It is suitable for applications needing true differential inputs to eliminate ground loops. Consider the 70mW power dissipation and verify if the available shutdown modes meet the system's power budget constraints.

Analog To Digital Converters (ADC) Part Context

The LTC1416 belongs to Analog Devices' family of low-power sampling ADCs. It is designed to simplify system design by integrating the sample-and-hold, reference, and timing logic into a single 28-lead SSOP package. This integration reduces the bill of materials and board space compared to discrete solutions.
