LTC2229IUH#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2229IUH#TRPBF is a 12-bit, 80Msps low-power analog-to-digital converter (ADC) from Analog Devices Inc. It operates on a single 3V supply (2.7V to 3.4V) with a typical power dissipation of 211mW. The device features a flexible input range selectable between 1VP-P and 2VP-P via the SENSE pin. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 70.6dB and a Spurious Free Dynamic Range (SFDR) of 90dB at a 70MHz input frequency. It utilizes a pipelined architecture with offset binary or two's complement output formats and includes internal clock duty cycle stabilization.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix #TRPBF corresponds to the Lead-Free Tape and Reel configuration as specified in the manufacturer's documentation. Confirm the temperature grade (C for commercial or I for industrial) matches the application requirements, as this is identified by the label on the shipping container. Ensure the component source is an authorized distributor to guarantee authenticity.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2229 for applications requiring high dynamic range and low power consumption at 80Msps. Choose the 2V input range for optimal SNR or the 1V range for improved SFDR. Ensure the driving circuit provides a source impedance of 100Ω or less per input to maintain performance. Verify compatibility with the required output logic voltage (OVDD) which can range from 0.5V to 3.6V.

Analog To Digital Converters (ADC) Part Context

The LTC2229 belongs to a family of low-power 3V ADCs available in various sampling rates. Pin-compatible alternatives include the LTC2228 (65Msps), LTC2227 (40Msps), LTC2226 (25Msps), and LTC2225 (10Msps). Higher speed variants in the same package include the LTC2253 (125Msps) and LTC2252 (105Msps). The device is housed in a 32-lead 5mm x 5mm QFN package.

Analog To Digital Converters (ADC) Replacement Considerations

For direct pin-compatible replacements within the same package, consider the LTC2228, LTC2227, LTC2226, or LTC2225 for lower speed requirements. For higher speeds, the LTC2253 or LTC2252 are options. Note that these parts may have different power consumption profiles and specific AC performance characteristics compared to the 80Msps LTC2229.
