LTC2270IUP

Analog To Digital Converters (ADC) Overview

The LTC2270IUP is a dual-channel, 10-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates with a sampling rate of 25 Msps and utilizes a single 3V supply for low power consumption. The device features a pipeline architecture supporting differential or single-ended inputs. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 61.8 dB and an Spurious-Free Dynamic Range (SFDR) of 85 dB at the Nyquist frequency. DC specifications specify ±0.1 LSB integral nonlinearity (INL) and ±0.05 LSB differential nonlinearity (DNL). The component is housed in a 64-lead QFN package.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix (e.g., #TRPBF) for packaging and RoHS compliance status. Confirm availability as distribution channels may list this part as discontinued or limited stock. Ensure the operating temperature range matches the industrial specification (-40°C to +85°C) required for the target application environment.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2270IUP when a lower sampling rate than the LTC2288 (65 Msps) is sufficient, offering potential power savings. Compare against the LTC2287 (40 Msps) if higher speed is needed. Verify that the input voltage range and drive requirements align with the source circuit capabilities before finalizing the design.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC228x family of dual 10-bit ADCs, which also includes the LTC2287 and LTC2288. These devices share similar architectural features and pinouts but differ primarily in their maximum sampling rates (25 Msps, 40 Msps, and 65 Msps respectively). They are designed for demanding imaging and communications applications.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same family include the LTC2287IUP (40 Msps) and LTC2288IUP (65 Msps), provided the higher sampling rates are acceptable. Cross-family replacements require careful evaluation of interface compatibility, power consumption, and pinout differences.
