LTC1402CGN#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1402CGN#TRPBF is a 12-bit, 2.2Msps sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from a single 5V supply or dual ±5V supplies with typical power dissipation of 90mW in active mode. The device features true differential inputs, an internal 4.096V reference, and a 3-wire serial interface compatible with DSPs. Key performance metrics include 72dB S/(N+D), –89dB THD at Nyquist, and 80MHz full-power bandwidth. It offers Nap (15mW) and Sleep (10mW) modes for power efficiency.

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type is 16-lead Narrow SSOP (GN). Confirm the suffix #TRPBF indicates tape-and-reel packaging. Ensure the C grade matches the required operating temperature range of 0°C to 70°C. Check RoHS compliance status as specified in the manufacturer's documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high dynamic range is required at moderate speeds. Use bipolar mode with dual supplies for optimal op amp performance or unipolar mode for single-supply systems. Consider the 80MHz full-power bandwidth for AC applications. Verify source impedance requirements against the acquisition time specifications if driving directly.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1402 series of serial 12-bit ADCs. The CGN variant specifically denotes the commercial temperature grade (0°C to 70°C) and the 16-pin Narrow SSOP package. The #TRPBF suffix indicates Pb-free lead finish and tape-and-reel packaging format.
