The LTC2248 / LTC2247 / LTC2246 are 14-bit 65Msps / 40Msps / 25Msps low power 3V A/D converters designed for digitizing high frequency, wide dynamic range signals. They are perfect for demanding imaging and communications applications.
The LTC2248/LTC2247/LTC2246 family are 14‑bit analog‑to‑digital converters that operate from a single 3 V supply (2.7 V‑3.4 V) and deliver low power consumption (205 mW/120 mW/75 mW). They provide up to 70 dB SNR and 80 dB SFDR over a wide input bandwidth, with no missing codes and a flexible 1 V‑p‑p to 2 V‑p‑p input range.
These converters are supplied in a 32‑lead plastic QFN package (5 mm × 5 mm) and are intended for high‑frequency, wide‑dynamic‑range applications such as wireless communications, imaging, ultrasound, spectral analysis, and portable instrumentation.
