LTC1420IGN#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1420IGN#TRPBF is a 12-bit, 10Msps sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from either a single 5V or dual ±5V supply, consuming 250mW of power. 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 of less than 0.25 LSB. At the Nyquist frequency of 5MHz, it achieves a signal-to-noise plus distortion ratio of 71dB and a spurious-free dynamic range of 83dB. The component is housed in a 28-lead narrow SSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix #TRPBF corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the industrial temperature grade (I-grade) covering –40°C to 85°C aligns with the operational environmental requirements of the target system design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution at 10Msps is required with low power consumption. Ensure the input signal range matches the available bipolar options of –2.048V, –1.024V, or –0.512V. Verify that the logic interface voltage can be supported by the OVDD pin, which allows connection to 3V digital systems.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1420 family of high-speed ADCs from Linear Technology, now part of Analog Devices Inc. The IGN suffix indicates the industrial temperature range variant, while the CGN denotes the commercial grade. Both variants share identical electrical performance characteristics but differ in their specified operating temperature limits.
