AD9484BCPZRL7-500

• Product Introduction

AD9484BCPZRL7-500 8-bit, 500 MSPS, 1.8 V analog-to-digital converter

The AD9484 is an 8-bit single-chip sample-to-digital converter (ADC) optimized for high performance, low power consumption, and ease of use. With slew rates of up to 500 MSPS, the device offers excellent dynamic performance for wideband carriers and wideband systems. All required functions are integrated on-chip, including a sample retainer and a voltage reference, to provide a complete signal conversion solution. The VREF pin can be used to monitor the internal reference or to provide an external reference (the external reference mode must be enabled via the SPI port).

The ADC requires a 1.8 V analog supply and a differential clock signal to maximize its performance. The digital outputs are LVDS (ANSI-644) compliant and support binary complement, offset binary, or gray code formats. The ADC also provides a data clock output for proper timing of output data.

The AD9484 is manufactured using an advanced BiCMOS process and is available in a 56-pin LFCSP package with a temperature range of -40°C to +85°C industrial temperature range. The product is protected by U.S. and international patents.

Product Focus  

1. 高性能。
   500 MSPS、250 MHz输入时信噪比维持在47 dBFS。
2. 易于使用。
   LVDS输出数据和输出时钟信号允许与现行FPGA接口。片内基准电压源和采样保持功能使系统设计更灵活，采用1.8 V单电源则简化了系统电源设计。
3. 串行端口控制。
   标准串行端口接口支持各种产品功能，例如：数据格式化、时钟占空比稳定器禁用、节电模式、增益调整及生成输出测试码等。
4. 与12位 500Msps ADC AD9434和12位250Msps ADC AD9230引脚兼容。
