AD6645 概述

The AD6645 is a high speed, high performance, monolithic 14-bit analog-to-digital converter. All necessary functions, including track-and-hold (T/H) and reference, are included on the chip to provide a complete conversion solution. The AD6645 provides CMOS-compatible digital outputs.

The AD6645 is built on Analog Devices’ extra fast complementary bipolar (XFCB) process and uses an innovative, multipass circuit architecture. Units are available in a thermally enhanced 52-lead PowerQuad 4 (LQFP_PQ4) package specified from −40°C to +85°C at 80 MSPS and −10°C to +85°C at 105 MSPS.
