Overview
The LTC2273IUJ is a high-performance, 16-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is part of the LTC2273 series, which includes the LTC2273 and LTC2272 models, differing primarily in their sampling rates. The LTC2273IUJ operates at a sampling rate of 80 Msps, making it suitable for applications requiring high-speed data conversion and precise signal digitization.
The ADC features a pipelined architecture and a high-speed serial interface compliant with the JEDEC JESD204 specification. It is designed to handle high-frequency, wide dynamic range signals with an input bandwidth of 700 MHz. The device includes a programmable gain amplifier (PGA) front end, allowing for optimization of the input range.
