LTC1420CGN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1420CGN#PBF is a 12-bit, 10Msps sampling analog-to-digital converter (ADC) housed in a 28-lead narrow SSOP package. It operates from a single 5V supply or dual ±5V supplies with a typical power dissipation of 250mW. The device integrates a high dynamic range sample-and-hold circuit, a precision reference, and a programmable gain amplifier (PGA). Key electrical specifications include an integral nonlinearity error of less than 0.35 LSB and differential nonlinearity under 0.25 LSB. AC performance features a signal-to-noise plus distortion ratio of 71dB and a spurious-free dynamic range of 83dB at the Nyquist frequency of 5MHz.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the component matches the specific 'C' temperature grade (0°C to 70°C) required for the application environment. Confirm the 28-pin narrow SSOP package dimensions align with the PCB footprint design. Ensure the ordering suffix '#PBF' indicates lead-free compliance as specified by the manufacturer documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 10Msps throughput are sufficient for the system requirements. Consider the integrated PGA if input signal conditioning is needed to maximize dynamic range. Verify that the available clock jitter does not degrade the 71dB SINAD performance, particularly for high-frequency input signals near the 100MHz full-power bandwidth.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1420 family of high-speed ADCs. The 'CGN' designation specifies the commercial temperature range and the 28-lead narrow SSOP plastic package. Other variants in the series may offer different temperature grades or package options, but the core electrical performance remains consistent across the family.
