LTC2299IUP#PBF

Analog To Digital Converters (ADC) Overview

The LTC2299IUP#PBF is a dual-channel, 14-bit analog-to-digital converter (ADC) operating at an 80Msps sampling rate. It utilizes a pipelined architecture and functions on a single 3V supply (2.7V to 3.4V). The device features a flexible input range of 1VP-P to 2VP-P and includes an internal reference. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 73dB and a Spurious Free Dynamic Range (SFDR) of 90dB at a 70MHz input frequency. Power consumption is rated at 444mW with both channels active.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free compliance when sourcing this component. Confirm that the package type matches the required 64-pin QFN footprint for PCB layout compatibility. Ensure the temperature grade corresponds to the intended operational environment, as specifications vary between commercial and industrial grades.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2299IUP#PBF for applications requiring low power consumption alongside high-speed digitization. The device supports multiplexed or separate digital output buses, offering flexibility in system design. Consider the 575MHz full power bandwidth when designing front-end circuits to ensure signal integrity at higher frequencies.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC229x family of low-power, high-speed ADCs. It shares pin compatibility with other members such as the LTC2294 (12-bit, 80Msps), LTC2298 (14-bit, 65Msps), and LTC2299 (14-bit, 80Msps). This allows for design scalability across different resolution and speed requirements within the same package form factor.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same family include the LTC2294IUP#PBF for 12-bit resolution at 80Msps and the LTC2298IUP#PBF for 14-bit resolution at 65Msps. These parts share the same 64-pin QFN package and supply voltage requirements.
