LTC1410CG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1410CG#PBF is a 12-bit, 1.25Msps sampling analog-to-digital converter (ADC) housed in a 28-lead plastic SSOP package. It operates from ±5V supplies with a typical power dissipation of 160mW. The device features a full-scale input range of ±2.5V and includes an internal 2.5V reference. Key performance metrics include ±1LSB INL/DNL, 71dB S/(N+D), and 82dB THD at the Nyquist frequency. It offers two shutdown modes: Nap (7mW) and Sleep (10μW).

Analog To Digital Converters (ADC) FAQ

What is the maximum sampling rate of the LTC1410?

The maximum sampling rate is 1.25Msps, which corresponds to a throughput time of 800ns.

How does the LTC1410 handle power consumption during idle states?

It provides two shutdown modes: Nap mode consumes approximately 7mW, and Sleep mode consumes approximately 10μW.

Can the LTC1410 accept single-ended inputs?

Yes, the differential input sample-and-hold can acquire single-ended signals by grounding the negative input (-AIN).
