AD9266-20EBZ

• Product Introduction

AD9266-20EBZ Single-Chip, Single-Channel, 16-Bit, 20/40/65/80 MSPS Analog-to-Digital Converter (ADC)

The AD9266 is a single-chip, single-channel, 16-bit, 20/40/65/80 MSPS analog-to-digital converter (ADC) that operates from a 1.8 V supply with built-in high-performance sample-hold circuitry and an on-chip reference source.

It features a multi-stage differential pipeline architecture with built-in output error correction logic that provides 16-bit accuracy at 80 MSPS data rates and ensures no code loss over the entire operating temperature range.

The ADC has a variety of built-in features that allow for optimal device flexibility and minimal system cost, such as programmable clock and data alignment, generation of programmable digital test codes, and more. Available digital test codes include built-in fixed and pseudo-random codes, as well as user-defined test codes entered via the Serial Port Interface (SPI).

A differential clock input is used to control all internal conversion cycles. An optional duty cycle stabilizer (DCS) is used to compensate for large clock duty cycle fluctuations while maintaining excellent overall ADC performance.

The interleaved digital output data is in offset binary, gray code, or binary complement. A data output clock (DCO) is used to ensure that the receive logic has the correct latching timing. Supports 1.8 V and 3.3 V CMOS levels.

The AD9266 is available in a 32-pin lead-free LFCSP package and is rated for an industrial temperature range of −40°C to +85°C.

Product Focus

1. AD9266采用1.8 V单模拟电源供电，而数字输出驱动器采用独立的电源供电，以适应1.8 V至3.3 V逻辑。
2. 取得专利的采样保持电路在最高200 MHz的输入频率下仍保持出色的性能，而且成本低、功耗低、易于使用。
3. 标准串行端口接口支持各种产品特性和功能，例如：数据输出格式化、内部时钟分频器、省电模式、DCO和数据输出（D15_D14至D1_D0）时序和偏移调整、以及基准电压源模式等。
4. AD9266采用32引脚LFCSP封装，符合RoHS标准，与10位ADC AD9609、12位ADC AD9629和14位ADC AD9649引脚兼容，因此采样速率为20 MSPS至80 MSPS的10位和16位转换器可轻松实现升级。
