AD9634-210EBZ

• Product introduction

AD9634-210EBZ 12-bit, 170 MSPS/210 MSPS/250 MSPS, 1.8 V analog-to-digital converter

The AD9634 is a 12-bitAnalog-to-digital converters(ADC) with sampling rates up to 250 MSPS designed to provide a solution for low-cost, small-size, wide-bandwidth, versatile communications applications.

The ADC core uses a multistage, differential pipelined architecture with integrated output error correction logic. The ADC has wide bandwidth inputs and supports a variety of user-selectable input ranges. An integrated reference simplifies design. A duty cycle stabilizer (DCS) can be used to compensate for fluctuations in the ADC clock duty cycle, allowing the converter to maintain excellent performance.

The ADC output data is fed directly to an external 12-bit LVDS output port.

Flexible shutdown options can significantly reduce power consumption when needed.

Setup and control programming is accomplished using a 3-wire SPI-compatible serial interface.

The AD9634 is available in a 32-lead LFCSP package and is specified over the industrial temperature range of −40°C to +85°C. This product is protected by a U.S. patent.
