LTC2299CUP#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2299CUP#TRPBF is a dual 14-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 444mW. The device features a pipeline architecture with a 575MHz full power bandwidth and supports flexible input ranges from ±0.5V to ±1V. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 73dB and a Spurious Free Dynamic Range (SFDR) of 90dB at a 70MHz input frequency. It offers integral nonlinearity (INL) of ±1.2LSB and differential nonlinearity (DNL) of ±0.5LSB.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF indicates a lead-free tape and reel configuration. Confirm the 'C' grade designation corresponds to the commercial operating temperature range of 0°C to 70°C. Ensure the package type matches the 64-lead QFN specification for proper PCB footprint alignment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel digitization is required at 80Msps with 14-bit resolution. The internal reference and SENSE pin configuration allow for input range optimization. Consider the 5-cycle pipeline latency and multiplexed output bus options for system timing constraints.

Analog To Digital Converters (ADC) Part Context

The LTC2299 belongs to a pin-compatible family of dual ADCs including the LTC2282, LTC2294, LTC2298, and others. These variants offer different combinations of resolution and sampling speeds, ranging from 10Msps to 105Msps, while maintaining the same 64-pin QFN package outline.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same family include the LTC2294 (12-bit, 80Msps) and LTC2298 (14-bit, 65Msps). Verify that the specific resolution and sampling rate requirements of the application are met by these substitutes before replacement.
