The AD6645 is a high performance, high precision, monolithic 14-bit analog-to-digital converter (ADC). All necessary functions, including track-and-hold (T/H) and reference circuitry, are integrated on a single chip.
The AD6645 is a high‑speed, 14‑bit ADC designed for multichannel, multimode receivers, base‑station infrastructures, and radar or imaging instrumentation. It offers IF sampling up to 200 MHz, a typical SNR of 75 dB at 15 MHz, and a two‑tone SFDR of 100 dBFS.
Available in 52‑lead PowerQuad (LQFP_PQ4) and thin‑quad (TQFP_EP) packages, the device operates from –40 °C to +85 °C (80 MSPS) or –10 °C to +85 °C (105 MSPS). Supply voltages are AVcc = 5 V and DVcc = 3.3 V, with a maximum power dissipation of 1.5 W.
