AD6644 概述

The AD6644 is a high speed, high performance, monolithic 14-bit analog-to-digital converter (ADC). All necessary functions, including track-and-hold (TH) and reference are included on- chip to provide a complete conversion solution. The AD6644 provides CMOS-compatible digital outputs. It is the third generation in a wideband ADC family, preceded by the AD9042 (12-bit 41 MSPS) and the AD6640 (12-bit 65 MSPS, IF sampling).

The AD6644 is built on the Analog Devices high speed complementary bipolar process (XFCB) and uses an innovative, multipass circuit architecture. Units are packaged in a 52-lead plastic low profile quad flat package (LQFP) specified from – 25°C to +85°C.
