ADC1207S080HW/C1:5

Analog To Digital Converters (ADC) Overview

The ADC1207S080 is a single-channel, 12-bit Analog-to-Digital Converter (ADC) designed for direct ultra-high intermediate frequency (IF) sampling. It operates at a maximum sampling rate of 80 MHz with a differential analog 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 utilizes a single 5 V supply for analog and digital logic, while the LVCMOS-compatible digital outputs operate on a separate 3.3 V supply. Key performance metrics include 90 dB Spurious Free Dynamic Range (SFDR) and 71 dB Signal-to-Noise Ratio (SNR) under specific test conditions.

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type HTQFP48 (SOT545-2) matches design requirements. Confirm that the industrial temperature range of −40 °C to +85 °C meets environmental specifications. Ensure power supply decoupling supports the specified voltage levels: 4.75 V to 5.25 V for VCCA/VCCD and 2.7 V to 3.6 V for VCCO.

Analog To Digital Converters (ADC) Selection Notes

Select this component when direct high-IF sampling is required to reduce RF front-end complexity. The low input capacitance (< 1 pF) is critical for minimizing external filtering requirements. Verify compatibility with PECL, TTL, or differential AC clock driving modes based on system clock architecture. Ensure the 12-bit resolution and dynamic range meet the signal integrity needs of the target application.
