ADC1207S080HW/C1:1

Analog To Digital Converters (ADC) Overview

The ADC1207S080 is a single 12-bit Analog-to-Digital Converter (ADC) optimized for direct Input Frequency (IF) sampling in ultra-high IF radio transceivers. It operates at a maximum sampling rate of 80 MHz with a differential input bandwidth of 375 MHz. The device features an internal front-end buffer providing less than 1 pF input capacitance, enabling flexible aliasing filter strategies. It supports full-scale adjustment from 1.5 V to 2 V peak-to-peak and utilizes a single 5 V analog/digital supply alongside a 3.3 V LVCMOS output supply. Key performance metrics include 90 dB SFDR at 225 MHz input frequency and 74 dB SFDR at 175 MHz.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Ensure that the HTQFP48 package dimensions and exposed die pad thermal requirements are integrated into the PCB layout design. Confirm compatibility with the required clock modes (PECL or TTL) during the schematic capture phase.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring direct high-frequency IF sampling without intermediate mixing stages. The internal buffer minimizes external filtering complexity due to low input capacitance. Ensure the system design accommodates the specified supply voltages: 5 V for analog and digital cores, and 3.3 V for LVCMOS outputs. Verify that the clock source supports the required PECL or TTL levels for the desired sampling edge.
